Summary:
Members of MS-13 have recently began trying to claim beach turf at Breakheart Reservation in Massachusetts. Breakheart is a forested lakeside park, which is popular with families and children. Recently, suspected members of MS-13 attempted to intimidate other park visitors and try to establish dominance over the beach area. Police have responded with shows of force and added patrols. However, on as late as July 4th there were fistfights involving gang members from the Chelsea area.

Analysis:
Interesting that MS-13 was trying to take over a park/swimming area. Presumably, they were either planning on using it for themselves or charging rent. For the record, Breakheart Reservation has no waves for surfing.
