well, they are going to find someone anyway, the police does not want to look incompetent and you can be pretty sure all the powers are pressuring them to do something because they don't want normies to realize rich people, celebrities and politicians are not gods and all it takes to kill someone is to get close enough to not miss. as you are aware i am not american but i sure wish this culture was imported here in my country, because things only ever get better when people do something.
