^^ hmm. there is a difference between govt. scanning your pc and govt. letting anyone to scan your pc.
yes. You wan't to keep information safe, keep it safe using required security methods.
Also, there is a difference between govt. scanning your pc whenever they want to and govt. keeping your pc open so that anyone can enter your pc.
If govt. thinks that this is necessary, I don't think there is any way that anyone can stop this.
If it is opposed, they will definitely use their own way to snoop into networks/pc's. Either way,they will do what they want to.
PS: Do you really think that nobody is snooping on your right now??
