Senseless violence

When did people start having targets on our head senseless killing of people in churches for no reason what so ever covering statues with black veils changing names of schools as well as streets just what in the hell do people think this will do? It's not going to change the past or make it go away all it is doing is showing just how in mature we have become letting some one else dictate how we run our country. Let's take back our great nation no matter what it takes stop all the bullshit and stop letting other's dictate our movements.
