Can I sue also?...
That they weren't beat enough.
Or maybe non-muslim who was there and felt threatened because the public pathway had been obstructed by someone who was obviously not paying attention to directions by safety personnel (i.e. the guards) could sue the muslims for endangering them? That would need to start with a very loud voice expressing concern for safety and terroristic threatening the muslim prayers obviously represent because of the clear view of the (former) World Trade Center from the Empire State Building.
