The decision not to charge the officers involved in the death of Alton Sterling is being met with anger by activists who say prosecutors are too deferential to cops. Is it true?

The Justice Department's decision not to prosecute Baton Rouge police revives questions about whether cops are reliably prosecuted when they kill.

A recent move by Congress to strip the Federal Communications Commission of the power to protect Internet privacy has provoked outrage among some, and state legislatures may try to weigh in.

After a two-year delay for repairs, the giant tunnel-boring machine has completed its mission far beneath the city's streets.

Police are trained to avoid warning shots for tactical and legal reasons. But this long-standing prohibition is being reconsidered under public pressure to reduce deadly shootings by police.

The technology has improved police conduct and led to a drop in certain types of cases. But the body cams have added many extra hours of work watching videos for police and public defenders.

President Trump is promising to crack down on crime. But police crackdowns have already been tried in cities such as New Orleans, which is now enduring a resurgence in homicide.

There's no legal definition for a "sanctuary city," but that doesn't stop people from using the term. We answer listeners' questions about what it means to be a sanctuary city.

A group of current and retired police chiefs are hoping to talk the Trump administration out of a return to what they see as a "lock 'em up" approach to law enforcement.

President Donald Trump has vowed to withhold federal funds from "sanctuary cities" to compel local officials and police to help enforce federal immigration law. As cities push back, it's not clear if the plan is workable.

It's unclear which jurisdictions would be covered by an executive order the president signed Thursday, or which funds would be withheld. Trump wants cities to cooperate with immigration enforcement.

The Justice Department has released a scathing report that accuses the Chicago Police Department of systematic use of excessive force.

Some police officials say their millennial-aged recruits are so used to communicating using social media that they need training in talking with people face to face.

Police officers say recent tensions in some communities have made their jobs more dangerous and have made some reluctant to do their jobs. The findings were part of a national survey by Pew Research.

Police say protests have made them feel more threatened and less inclined to do their jobs. Sen. Jeff Sessions, Donald Trump's pick for attorney general, echoed that sentiment in his testimony.

Many officers believe they're being targeted. But while more were killed in ambushes, statistically it is a small number. Still, as one former cop says, pulling up a spreadsheet doesn't help.

In the U.S., local jurisdictions choose whether to help with federal immigration enforcement, but in Canada and Mexico, it's different. Cooperation is expected.

A Marine-turned-cop was fired after he did not shoot a man who had a gun. His Marine training led him to believe there wasn't clear hostile intent; his bosses say he risked other officers' lives.

Donald Trump wants to punish local law enforcement that doesn't cooperate with immigration law, but the decisions to enforce are varied, and some worry it could lead to abuse.

The election of Donald Trump is a balm to police around the country, who say they have felt under siege. But others in the law enforcement community expect reforms to departments' methods to continue.
