Washington gun debate wasn’t always stuck in neutral

“There ought to be a law.”

That’s a common American refrain on a long list of issues, from unsolicited phone calls to opioid abuse, and Congress often acts. But this week’s school shooting in Parkland, Florida brings attention to one prominent issue where that cause-and-effect rule no longer seems to be true: gun laws.

Three of the 10 biggest mass shootings in U.S. history have now taken place in the last five months and the question, as it always is after the all-too-common events, is will Congress step in? CONT.
