My sarcasm detector did not go off either.
After reading the article, I couldn't help but empathize with the victim's parents. Their son got gunned down, cop or not. It's their son, and its a human being.
Mature the fuck up. How would you feel if one of your family members, mother/father.. brother/sister... son/daughter was brutally gunned down for no reason. Then, to make that worse- the murderer is able to avoid punishment, simply by playing 'dumb'.
So no, I don't understand the "LOL" response either. That is NOT sarcasm.
