Sounds like you did a good job of keeping your cool and not to panic. It ended better for you and him. I would not have been so calm I think. Well played sir.
On an episode of "Self Defense TV" a while back, they said you're more likely to get a quicker response time from law enforcement if you call in and say home invasion in progress rather than prowler or attempted break in.
I live out in the country in a rather large county in Kansas that has maybe 3 deputies on duty at night scattered to all parts of the county. It would take a while for one of them to get here anyway. So I'm on my own if something like that were to happen.
I fully respect LEO, but they have a hard job and most of the time end up cleaning up rather than stopping crime.
