I was wondering if anyone had tried OC foggers/grenades. What do you think about using such for home defense? The thought is if someone breaks in pop a fogger, toss it down the hall, shut the bedroom door, put on the gas mask, and wait for the cavalry. Seems pretty effective to me. What do you think? They can be found at http://www.guardianproducts.com Another important question, Would this be legal for this use in California? Thanks.
