From New York City to Fargo, North Dakota, cities across the United States say they are issuing curfews to keep the peace.A curfew allows police the ability without any other reason to threaten to arrest or detain crowds of protesters that linger or groups that appear to be a danger to order.These curfews can be a deterrent to get law-abiding citizens to head home and allow law enforcement to focus their efforts on the unrest, not getting bogged down with simple violations.But the deadlines aren’t hard and fast — many of them have exceptions for people heading to and from work, reporters, public transportation and even people buying groceries.Many protesters have routinely disregarded the curfews, and some police departments have actually allowed peaceful demonstrations to continue even after curfew while focusing their attention on violent unrest.Curfews like these are commonly used in natural disasters like hurricanes, floods and tornadoes to allow police to stop anyone on the streets and prevent stealing or looting.Some civil rights organizations think hastily issued curfews are unfair and against the First Amendment. The American Civil Liberties Union of Northern California argued that curfews give police too much discretion over whom to arrest, The Associated Press reports. 1307

HOOVER, Ala. (AP) — Police in Alabama on Saturday were searching for a gunman whom they believe was responsible for shooting two teenagers at a shopping mall on Thanksgiving night.The incident began with a fight and shooting in suburban Birmingham at the Riverchase Galleria, a mall crowded with Black Friday bargain hunters. An 18-year-old was shot twice and a 12-year-old bystander was shot in the back.An officer responding to the scene then shot and killed 21-year-old Emantic Fitzgerald Bradford, Jr. of Hueytown. Police said Bradford was fleeing the scene and was brandishing a weapon.Police initially told reporters they thought Bradford had shot the teen after a fight but retracted that statement Friday night."New evidence now suggests that while Mr. Bradford may have been involved in some aspect of the altercation, he likely did not fire the rounds that injured the 18-year-old victim," Hoover Police Captain Gregg Rector said in a statement.Police said they "regret that our initial media release was not totally accurate."Rector said investigators now believe that more than two people were involved in the initial fight ahead of the shooting, and that "at least one gunman" is still at large who could be responsible for the shooting of an 18-year-old male and 12-year-old female.Video posted on social media by shoppers showed a chaotic scene as shoppers fled the mall, which closed for the remainder of Thursday night.The Alabama Law Enforcement Agency has taken the lead role in the investigation since it is an officer-involved shooting.Hoover police asked for anyone with information, photos or video evidence of this crime scene to please contact investigators.A witness, Lexi Joiner, told Al.com she was shopping with her mother when the gunfire started. Joiner said she heard six or seven shots and was ordered, along with some other shoppers, into a supply closet for cover."It was terrifying," Joiner said.A woman who described herself as the mother of the injured 12-year-old posted on social media that the girl was on a Black Friday shopping trip with other family members when the shooting happened, and didn't immediately realize that the pain in her back was from a bullet."She was hurting a lot, but very brave and positive as always," the mother wrote after seeing the girl when she arrived at a hospital.Hoover police said Friday morning that the girl was in stable condition.The officer who shot the gunman was placed on administrative leave while the authorities investigate the shooting. The officer's name was not released. The officers were not hurt.The Riverchase Galleria mall bills itself as the largest enclosed shopping center in Alabama, with more than 150 stores. 2718

Health departments around the U.S. that are using contact tracers to contain coronavirus outbreaks are scrambling to bolster their ranks amid a surge of cases and resistance to cooperation from those infected or exposed. With too few trained contact tracers to handle soaring caseloads, one hard-hit Arizona county is relying on National Guard members to pitch in. In Louisiana, people who have tested positive typically wait more than two days to respond to health officials — giving the disease crucial time to spread. Contact tracing tracks people who test positive and anyone they’ve come in contact with. It was challenging even when stay-at-home orders were in place, but it’s exponentially more difficult now. 724

Heads (and eyes) up, skywatchers! The annual Perseid meteor shower is underway and will hit its peak this weekend.The meteor shower, so named because the meteors appear to come from the constellation Perseus, lasts for several weeks – from July 17 to Aug. 24 – but peak meteor activity will take place between about 4 p.m. ET on Sunday, Aug. 12 and 4 a.m. on Monday, Aug. 13, according to NASA.During the peak, one can expect to see as many as 60 or 70 meteors per hour.Night sky conditions should be great for meteor viewing: The peak coincides perfectly with the new moon, meaning the sky will be plenty dark and meteors will be easy to spot. Most meteor showers are best after midnight. 702
