OK then... as a professional programmer of many years, I can tell you that I could get you on the FBI’s target list if I knew the URL they were monitoring, without any action from you if you have a wireless network and I was physically nearby; or alternatively, I could get you on the list by simply enticing you to click a totally innocent link, which would load a totally innocent-looking webpage which would give you no reason to believe that you just created probable cause for a search warrant.
See my post #119 for a (non-functional but conceptually correct) version of the code. It’ll scare the crap out of you.
And stay away from fluffy bunnies!
