Are those supposed to be trigger locks then the guns? I thought trigger locks are supposed to block the rear side of the trigger. Maybe they do but not visible in the pic.

Even if someone could make all the guns disappear the people who are determined to kill other people will use something else. It is estimated that over 1200 intentional homicides are committed every day world wide. I doubt the lack of guns would make much of a difference in that.

I am not opposed to gun ownership at all and it seems to me there are plenty of gun control laws in place already but they are not properly administered and enforced. More laws are not going to change that one little bit.
