NASHVILLE, Tenn. — There are problems with how security for a Nashville Scientology event was handled, and laws appear to have been broken.

In a home video, a group of protesters walk toward the Church of Scientology on the day of the church’s grand opening and are stopped by security guards, who knock one protester to the ground and have him arrested for criminal trespass.

The altercation happened 400 yards from the church, on the other side of the street.

Public Works pulled all of the permits taken out for the Scientology event. The permits — all of them for sidewalk closing and lane blocking — are for the wrong day. They’re for the day before the event and expire before the scuffle occurred.

In addition, three of the five security guards were off-duty Spring Hill police officers working in Nashville, which can only be done if local police are notified and officers are wearing uniforms clearly identifying them as off-duty police officers.
