wow we should re-label this thread as "N800 and self-defense." maybe somebody could install a taser for the N800. the input button could act as a trigger. that would be cool. seriously, thx everyone for the concern. my training has taught me to leave quickly if a gun or knife is present. however, i am trained to disarm blades, but that would be a last resort. on the other hand, retractable batons are quite easy to carry (and legal). two batons in concert can be devasting. guns, again, are a different matter. on another note, the police officer who helped us had some really good ways to protect the house. i think i'll try some of her suggestions before installing lexan windows. anyway, keep an eye on your tablet.
