I've heard a lot of good things about the Dallas PD, and it's sad that they were lumped in with crooked cops a few states away and lost 4 good officers in the tragedy a few days ago. Even after that they had to deal with a bomb threat and threats from a Houston gang. Still they came out of all of this as professional as possible and even now are trying to defuse tensions. Hopefully their officers don't get caught in the cycle and become more paranoid and trigger happy after all of this.
