No, only dumb lefties thought gun bans would stop this. And yes I said gun bans, thats what crazy lefties want. Just like how crazy righties want Muslim bans and LGBT bans and even if they wont say it now they also want asian bans, black bans, atheist bans, and infinite other bans.
as I said elsewhere with regards to liberal hypocrisy is that there is much anger around the supposed "ban" and how the lefties feel that the temporary hold violated the constitutional rights of Green Card holders or those on work visas, yet it seems when talking about gun control, which is a constitutional right "extreme vetting" with often lengthy waiting periods and exceptionally thorough background checks is perfectly acceptable to the folks who are bent about this.
for what its worth I am ok with vetting in both cases but feel that it wouldn't stop tragedies from happening.
