Another Shooting at a Car Show

Here the media is discouraged from posting gang related crime. The reasoning behind it is that the police don't want to glorify it for the public or the gangs themselves.
What are the thoughts of everyone on here that they think would help slow / stop the gun violence? Something needs to happen, more gun laws is not the answer as they don't enforce what's on the books now. What about no probation for gun offenders?
