A teacher's assistant handbook is causing some controversy at the University of Maryland. The handbook was meant for Computer Science TA's and had separate instructions for both men and women. Now, some people are saying the comments made inside are sexist.It tells the women their students may have trouble accepting they are in the scientific field because it's a male associated activity. The handbook continues to say this is good practice for the real world because students may not be the only ones having trouble accepting women as a professional. 607

A starting point for investigators trying to trace the bombs sent to Democratic figures and CNN this week: the postmark.But in some cases, it appears to be a missing clue.The postmark typically indicates when and where the mail was sent from and is marked over the stamps -- "canceling" them, and preventing the stamps from being reused. Unlike stamps, most of which cannot be traced, the impression left by a postmark or mail meter is distinctive and can help investigators focus their search.A postmark is visible in a photo of at least one of the packages seen by CNN. A postmark is not visible in photos of several other packages shared with CNN -- only adding to the questions about their origins.The lack of a postmark is very rare, according to Nancy Pope of the National Postal Museum.A postal inspector who spoke to CNN on the condition of anonymity indicated it would be very unusual for a piece of mail to leave the facility where it was dropped off for delivery without such a mark.That could indicate that a sender or senders were working in multiple diverse geographical areas, including New York, Washington, Florida and California.Another source told CNN it is possible some of the stamps may not have been canceled because of the package's soft sides and odd shape, which would make it difficult to stamp.The US Postal Service's website also says mail may not be postmarked if it was processed through a meter or if the postage was paid by permit or precanceled stamp. None of those appear to apply to this situation.Adding to the mystery are post office markings on one of two packages sent to former Vice President Joe Biden indicating the stamps on the package did not cover the cost of the delivery, and additional postage is due.That suggests the package was weighed at some point during the shipping process, a former postal inspector told CNN.It was unclear from the photo whether that package had been postmarked.Postmarks can be applied by machine and by hand, depending on how a piece of mail is sent, according to the Postal Service. When mail is run through an automated system at a processing distribution center, the postmark is applied, and the mailed item is screened by a biohazard detection system.It was not clear why postmarks were not visible on several of the packages, and the US Postal Inspection Service provided a statement to CNN that did not address the question."The U.S. Postal Service has developed a comprehensive approach to protecting the mailsystem by utilizing a targeted strategy of specialized technology, screening protocols and employee training," read the statement.The statement noted its Dangerous Mail Investigations Program includes law enforcement officers who "are trained to recognize the common characteristics of suspicious mail and are highly proficient in the use of state-of-the-art equipment to include portable X-ray machines." 2907

A San Diego bail bondsman is disputing a controversial Facebook live in which the narrator says his agents were turning in a suspected undocumented immigrant.The video, shot Monday by Ryan McAdams, shows Watkins employees turning a Latino man into central jail. McAdams, wearing a Watkins hat, narrates the video, saying the man was at risk of skipping trial and costing Watkins ,000. He added commentary that drew criticism from immigration advocates. "He's in here hiding under sanctuary status right now," McAdams says in the nine-minute video. "Let ICE (Immigration and Customs Enforcement) deal with him."Jerald Watkins, who co-owns Watkins Bail Bonds, said he watched that video in shock. He said immigration status doesn't matter. "As long as you appear at your court dates, that's all we're asking," he said. Watkins said his workers took the man in after he changed his address and phone number, plus a warning from his co-signors that he may skip trial. "The family called and said look, this guy's acting shaky, we don't want to be on the hook for ,000," he said. Watkins said McAdams isn't his employee. He simply knew the agent, who let him ride along while he broadcast it on Facebook."Yeah, I'm not happy about that," Watkins said. "That's just some private citizen doing what he's going to do."McAdams told 10News Monday he wanted to inform the public."I'm just trying to keep people up to date," he said. But Watkins says immigration status had nothing to do with the case. In the Facebook video, McAdams said the man was suspected of driving under the influence. But Watkins said he was suspected of providing false information to police.He declined to identify the man.    1758
