I like areosol deterents myself. Ive once watched a rather idiotic person spray starter fluid over a lighter. Sure it will light your home on fire, but it doesnt seem that there are any better non gun solutions. Maybe keep a can of muriotic acid to throw it in a intruders face. How come in a effort to claim there are tools more as good as guns, people will make themselves look like idiots and will rely on ineffective solutions that present more danger to themselves?
