Mr. Bean may I inquire who told you that? Obviously that person who told you is making a black propaganda against Davao, that's how ugly that person's attitude is just so to give you false impression against Davao.
That source of black propaganda about XDS is trying to mislead you, the truth is far from it. He was probably referring to an imaginary vigilante group supposed to eliminate criminals like thieves, pushers, holduppers, swindlers, snatchers in which obviously you're not such a person. You are actually very safe please don't mind the black propaganda lie being told to scare you. There are many good traits of Filipinos, but the envious nasty ones aren't one of such traits and he's showing his ugly green-eyed side, that person who tried to scare you is lying to you.
