It seems that the cops are trying to make their presence felt in the new jungle.
Running above and alongside it, the highway gives a good vantage point for the police to look in on the new jungle. So far there have been many visits from police, just sitting there and spying in from the highway.
There have been reports of police inside the jungle, looking around the camps people have built, and of a helicopter over the space.
Also, it seems that people are being controlled when they come back into the jungle.
