You're right (in your way).

Trump might not be able to stop these mass shootings, but RANTING FOR, AND SUPPORTING THE NRA are definitely not helping the cause either. Right?

As the President, he should have done something to protect Americans, instead of waiting till a shooting occured, and then all he did was send the useless "Thoughts and Prayers" to the innocent victims and a few weeks later, everything is back to square one and the NEXT mass shooting will unexpectedly happen AGAIN AND AGAIN.

So now, tell me, can Trump do anything about that, as you asked?
