Please consider employing the very effective, non-lethal riot control measure being used successfully around the world in places like the UK, Japan, etc. It is the use of high pressure water cannons containing identifying ink that lasts up to 3 weeks on rioters and looters. These cannons are mounted atop very rugged military style vehicles that are heavily armored and impossible to break into or be slowed down by riot crowds. In viewing film from the latest riots, tear gas is not effective and single hand-to-hand combat is not working effectively. Please consider this proven, effective riot control method ASAP.
