Gang related

Last night on Reina street there was a group of boys around 11 with bats that were fighting with someone in the end of the court, smashing car windows. It was the most scariest thing I had ever seen and still am shaken by it. My son thank God was at the gym but neighbors cars got hit and they escaped. There are no lights on our street so its hard to see or describe them but by the time the police cars came they had escaped. What I heard that it was gang related and it was a warning to the people that live in our area that they were targeting. I dont feel safe anymore here and wonder if I need to get securty cameras ! Does anyone know the details yet?
