Now is not the time for silence. It's time for outrage.

Our hearts go out to the families and friends of the hundreds of people that were killed or injured at the Mandalay Bay Casino mass shooting in Las Vegas, the worst in the nation's history. But sympathy will not save the 33,000 Americans who will be killed this year by gun violence.

Legislators beholden to the gun lobby will no doubt say now is not the time to talk about gun laws. There is no other kind of attack on Americans that is met with this level of indifference. It needs to stop.

Right now Congress is considering deregulating silencers which would make it harder to identify from where gunshots are coming in active shooter situations. The House is close to passing a bill making it easier for people to carry concealed weapons to any state in the nation with not so much as a background check.

Tell Congress #Enough. Sign this petition to tell Members of Congress to:

Vote no on H.R. 3668, the SHARE Act that would gut long-standing regulations on silencers and loosen restrictions on armor piercing bullets.

Block H.R. 38, the Concealed Carry Reciprocity Act that would force states to honor the concealed carry weapons permits of every other state, regardless of how lax the other state's law.

Ban weapons of war: assault weapons and large capacity magazines, which have no place in the hands of private citizens.
