muslim terrorist kills 5 with bow and arrow

why didnt he use a knife or baseball bat? why didnt he attack the
police? why didnt the police take him out immediately?

answers - he didnt attack the police because he was a coward - he
wanted to attack unarmed people

answer - he didnt use a knife or baseball bat or club because he
wanted to be memorable - he wanted fame - he wanted drama

answer - unknown why the police didnt kill him immediately - maybe
rules of engagement are too strict - maybe police are poorly trained
and equipped and staffed
