Violence in P.A.

I grew up in P.A. and my parents and brother still live there. Both my Dad and brother have had their lives in danger within the last year. A while ago, my dad was working (he used to deliver pizza as a side job) and he was jumped by a group of people and had his wallet stolen and was beaten to within an inch of his life, now every time I see my dad I'm reminded of this incident because all of his front teeth were knocked out. I'm posting about this now because last week my brother was at a going away party for one of his friends (not the type of party I would find myself at, but that should be irrelevant). Again, a group of people decided they wanted to crash this party, and thoroughly kicked the crap out of two of my brother's friends before one of his other friends called him to come outside to try and help the situation (this angers me, I don't know what they thought he was going to do). When my brother got outside one of the crashers pulled a knife, and my brother began to fear for his life, and made a poor decision, which I can't post here because it could get him in trouble. Let's just say the crashers are lucky to be alive, and my brother is lucky to not be in jail. I'm still stunned by this incident, can't believe this happened again to another member of my immediate family, and can't believe what my brother tried to do. I'm angry and confused and feel like I should do something but I don't know what. Not even sure what to pray, except maybe that my family's hearts would not be hardened by racism any further. God help us.
