SAN DIEGO (KGTV)-- Protests around the nation have put police officers' less-lethal use-of-force under the microscope. A criminal justice professor explained the protocols taught in the Police Academy, and what is considered appropriate and excessive.La Mesa Police used tear gas against riotous protestors rushing Police Headquarters on May 30, 2020."These are things that are designed to get people's attention, to shock them, to say get back," former El Cajon police officer and now criminal justice professor, Kevin LaChapelle said.If the violent protestors disperse, LaChapelle said these less-lethal weapons are serving their purpose. He said in the Police Academy officers are taught to face threats using the "Force +1" method."If somebody is presenting a particular level of force towards me, I can respond with that force and then one more level to basically control the situation."According to the National Institute of Justice, there are five basic levels of "use-of-force" to diffuse a situation.1. It begins with officer presence, in which there is no use of force.2. Then come verbal commands, such as an officer asking for identification or telling someone to 'Stop!'3. The next level is empty-hand control, where an officer could grab, hold a person.4. Then come the less-lethal methods, including a baton, taser, projectile, sound, or chemical sprays.5. The last resort is lethal force or the use of a firearm.LaChappelle said officers primarily use projectiles to control riots. Pepper bullets are normally deployed onto the ground, and when they skid, they emit an uncomfortable spray. Sound, light, or rubber bullets are aimed at or below a person's torso, which can cause bruises. The same go with beanbags, which can be filled with anything from styrofoam to harder materials."When people say, 'This is too uncomfortable, and I can't handle this. I'm going to stop. I'm going to leave,' that is what you're hoping for," LaChapelle said.But to avoid these violent clashes, LaChapelle believes it is crucial to build relationships and dialogue between departments and the community."Lawlessness isn't the answer, but there has to be reform because what's worked in the past does not work for the future," LaChapelle said.ABC10News asked the La Mesa Police Department for its exact protocols for the use of projectiles during violent riots. They sent us a link to their less-lethal weapons manual. Its philosophy states: 2448

SAN DIEGO, CA — SAN DIEGO (KGTV) - The City of San Diego calls it the "Get It Done" App, but a Normal Heights man says he wants to know when work will get done."They block the sidewalk. They've ripped through my canopy. They've killed my two lemon trees," said Mike Scaglione as he stood in front of his home. He's referring to the damage caused by palm fronds that fall from two trees on city property he says are in serious need of maintenance. "It'll be seven years tomorrow that I've lived here and in that time frame I've probably picked up 3 or 4 hundred palm fronds."Scaglione said he's been trying for several months to get the city to keep up with the trimming of the two palms outside his home. "They say they're going to, or they direct me to somebody, but it just keeps going no where until it's a dead end." Scaglione says aside from the damaged to his property, he fears a potential for much worse. "Its kind of hard to see," he says, grabbing a palm frond from a pile collected near the trees, "but if you run your hand along here there's a pretty jagged toothed edge on here that if it was to land on somebody it could rip them pretty nicely."Scaglione has been using the city's Get It Done app. Past reports show crews have responded to clean up the fronds once they're on the ground. But when it came to a neighborhood tree trim last October he says, "They came through here and trimmed every tree on the block except mine." Scaglione said he asked the crews why. "They didn't have anything that could get up that high." Scaglione estimates the trees at 40 to 50 feet.In response to an inquiry by 10News, a city spokesperson sent an email explaining San Diego is on a two-year cycle for trimming city owned palm trees. Scaglione's block was on the schedule for October. But there's still more work to be done. So, does that mean the trees in front of Scaglione's home will be trimmed? "Yes," replied the spokesperson, "It is on the schedule." Though Mike feels like he's been here before."They would look into it when they were doing similar work in the neighborhood. Again, I have no idea what that means either." The rest of the city's response is summarized as follows: 2203

SAN FRANCISCO (AP) — Firefighters in California are racing to slow the spread of wildfires that burned nearly one million acres in a week and destroyed hundreds of homes. The fires have killed five people, torched nearly 700 homes and other structures and forced tens of thousands from their houses. Light winds, cooler nighttime weather helped fire crews make a bit of progress on Saturday. But their efforts could be hurt by warm, dry weather, erratic wind gusts and lightning in the forecast. Firefighters are beginning to get help from other states and President Trump issued a major disaster declaration to provide federal assistance. But the state's top fire official warned “the worst is not behind us.” 718

SAN DIEGO, Calif. (KGTV) - An open letter to the World Health Organization titled “It is Time to Address Airborne Transmission of COVID-19” is signed by 239 scientists from 32 different countries and highlights the importance of acknowledging and protecting the public against the possibility that coronavirus can be spread through the air. One San Diego scientist who signed is from the UCSD Scripps Institution of Oceanography, Doctor Kim Prather.The idea shared is that COVID-19 can be spread from aerosols, which are particles that float in the air rather than dropping to the ground like a droplet. An infected person breathes out aerosols that are suspended in the air, then another person walks through that air and breathes it in.It’s no secret that heath officials have discussed the importance of good airflow to stop the spread, but this paper says leaders like the WHO are not recognizing the possibility that it is airborne and the “lack of clear recommendations on the control measures against the airborne virus will have significant consequences: people may think that they are fully protected by adhering to the current recommendations, but in fact, additional airborne interventions are needed for further reduction of infection risk.”Researchers say wearing masks and social distancing are important steps to stopping the spread, but want to also emphasize that other steps need to be taken to stop the spread through the air. Some steps for public places include getting better ventilation and decreases crowds. At home, people can open doors and windows and also use air purifiers to help. 1618
