The peaceful protests that took place in Baltimore had no effect so they resorted to violence. Think of it like this, if you whisper in someone's ear and they can't hear you what do you do? The logical answer would be to raise your voice. I can't stand and support the riots in all aspects though, there will always be those who take the situation for granted and riot simply to loot and raise hell. I'm just saying that I can completely see where the rioters are coming from.
