5 out of 5 stars Accept no substitutes when casually repressing students, November 21, 2011
Whenever I need to breezily inflict discipline on unruly citizens, I know I can trust Defense Technology 56895 MK-9 Stream, 1.3% Red Band/1.3% Blue Band Pepper Spray to get the job done! The power of reason is no match for Defense Technology's superior repression power. When I reach for my can of Defense Technology 56895 MK-9 Stream, 1.3% Red Band/1.3% Blue Band Pepper Spray, I know that even the mighty First Amendment doesn't stand a chance against its many scovil units of civil rights suppression.
When I feel threatened by students, no matter how unarmed, peaceful and seated they may be, I know that Defense Technology 56895 MK-9 Stream, 1.3% Red Band/1.3% Blue Band Pepper Spray has got my back as I casually spray away at point blank range.
It really is the Cadillac of citizen repression technology.
Buy a whole case!
