First of all let me say I'm glad Im not in your shoes, as for advice? The use of pepper spray, CS, tear gas, other chemical weapons, in the end may solve the immediate problem at the time but may also lead to just pissing him off more when it wears off. security windows, doors etc. Great for inside, But you have to be inside to be effective. You could go to the police (take a pizza) and make complaints or at least make them aware of your situation. I would find out legally what would happen if you killed the guy even though you were protecting yourself and family from bodily harm. remember this is there country and YOU are the foreigner here! the same laws may not apply to you. If you're a renter, as hard as it may be I might suggest moving. ( which is probably what the police will advise you to do). Post like this makes me thankful my biggest problem is the noise from the resort next door till 2-3am in the morning on weekends and holidays. (it wouldn't be so bad if some of them could actually sing, but not) Good luck to you, hope it works out for the best.
but a reality!?!? Loads of concrete walls here with razor wire or broken jagged bottle edges built in. Pretty standard for all windows to be covered in bars here as well. Yards with dogs tied to a tree with a very short rope is secondary security as well. Most of this would be left for slums and ghetto properties in my home country. It's just normal here....
Think that's fun...try doing DI School...By the time that was over I could breathe that sh!t 24 hours a day...Not that I miss it...
Any better prices in town than the p1500 in front of Jollibee at Robs for a stun gun? Maybe a gun shop?
