Nope, we weren't allowed to take them in the fence to start with. The riots were at the staff entrance before we got inside.
Problem is RF doesn't respect boundary lines. If the jammer were to prevent someone just outside the facility from calling 911 in an emergency the lawsuits would be filed before the funeral.
I just spent a week in an area (N WI) with no cell phone coverage.
Who would I have sued if I had an accident?
Signs could be posted *NO CELL PHONE COVERAGE IN THIS AREA*.
The prisoners being able to run the place AND their crews on the outside is pathetic and MUST be stopped.
PS - Riots can be handled by 12 ga slugs and/or buckshot.
