My comment:
(a) It looks like the essay was written in mid-2000s.
(b) "美国不安全, 95% 的家庭忘了装防盗网/防盗门/防盗窗; 也奇怪, 那些小偷都到哪里去了呢? "
Well, I have been wondering about the same thing since coming to US. (In Taiwan, doors and windows are like those in American prisons, even in top floors. Sometimes residents die when they are trapped inside by fire.) My own conclusion is that home invasion is a felony under Massachusetts state law, carrying a stiff sentence once convicted. So is the crime of possession of burglary tools.
