Now you're getting to the meat of the story, Boaz, but you won't find the answer from the media covering the story or asking DR lefties.
The area within 1000 feet of public housing is a Drug Free Zone in Pennsylvania, apparently, like most every other state. Loitering and Wandering laws in Drug Free Zones are set by the state, not the municipalities, and are biased towards a presumption of malfeasance for those found standing or walking around.
In my opinion, these laws are the story that is not being covered. It is not a municipal issue unique to Chester Township. Loitering and Wandering laws in Drug Free Zones including schools and public housing is a nationwide practice; one can imagine how enforcement can be problematic.
It could be that the details of the arrests of the Briggs family members aren't that problematic. The media outlets covering this story are carrying the water of the family's attorneys, while ignoring or glossing over the obvious question of how did the incidents start.
At one point in the longer video, Ms. Briggs says at the onset of the first incident she told the boys to get in the house, seemingly aware of the loitering laws. Later she says the boys were playing in the yard.
Maybe the lawyers are completely inept, and forgot to lead with their best details, which would be about the initial interactions with the cops that led to 15 squad cars being dispatched.
Honestly, kicking a squad car seems like valid probable cause for an arrest. The charges in the arrests include loitering,failure to disperse, disorderly conduct, and resisting arrest.
Why haven't the media obtained and reported on the police reports?
This could turn out to be a milestone case against Drug Free Zones, but it doesn't seem like the details are there to support the lawyer's version of things.
