US attorney general: ?going to take action? after Florida shooting

WASHINGTON (Reuters) - U.S. Attorney General Jeff Sessions on Thursday pledged the Justice Department would work to vigorously enforce federal gun and violent-crime laws and preventively identify potential mass shooters, as the country reeled from a Florida school shooting that killed 17 people.

?It cannot be denied that something dangerous and unhealthy is happening and we are, once again, watching the images of our children ? terrified ? streaming from their school with their hands above their heads,? the top U.S. law enforcement officer told a meeting of sheriffs. ?We are going to take action. We must reverse these trends.?
