OK, so I have decided that my example of not having the intention to commit the crime is a bad one as it has been flagged up by everyone regarding how in the UK you can indeed be arrested for this.

heres my solution to the situation in the UK. If you are EVER planning on sleeping it off in the car, get a breathalyzer locking cabinet for your keys.

this way you can prove unambiguously that you are unable to operate the vehicle even if you wake up and are over the limit... there.. problem solved. Now lets get back on track about the right to read all communications.

even if they backdoor all chat messages, you can still use your own encryption within that channel. Everyone can do this using free open source software and even custom keyboards in android (I don't use iPhone so I don't know about them).

What happened to good old fashioned spycraft following people around and occasionally plutonium pelleting someone in the leg with an umbrella.
