I'm not scared of terrorists. What I'm truly scared of is that if another significant terrorist attack happens, whether or not the NSA's powers have been curtailed, DiFi, Rogers, King, Clapper, et all, will cry "See?! That's what happens if we don't have the ability to collect everything!", using the tradedy to drive us even further towards an Orwellian survailance state.
I haven't seen anyone mention yet the fact that if this was implemented in the US there would most likely be a rampant rise in drug addiction, gambling, prostitution, alcoholism, or other vices, as well as all the social ills that go along with these issues. But at least musicians could sit in their NY loft writing music which they can freely share in between rounds of shooting heroin. Oh, and no more piracy. Bully for us.
