Would you give the keys to your house to the government and just expect that they would behave and not ransack your house while doing the “Looking for the terrorist” game? My secret stuff is just that “Secret”. I don’t need a reason for it to be secret and I’m not going to justify making it secret. The government wants the keys to the kingdom to protect us from the criminals. I use security and encryption to protect myself from the criminals. I am proactive and don’t need the government to have a backup set of keys to my stuff.
