Feeling Defeated

I am feeling so disheartened, saddened, defeated, frustrated and angry with all the horrible shootings happening around the U.S. These are innocent people's lives - gone forever. It makes me sick when people brush off gun control because "guns don't kill people, people kill people".  Well, people are not perfect.  People are fallible and don't always act with control; despite what their background check may state.  Training doesn't guarantee that a person will always react rationally when under duress.  I can't understand how we, as a nation, continue to let these tragedies happen. Why do we allow these senseless deaths?!  It breaks my heart.
