Agree on harsh punishment for hacking phones or any other electronic device. It's theft via wire fraud and should be prosecuted as a federal crime.
Off topic, but I'd add misbehavior on commercial aircraft. This is one of the few areas where the feds have sole control. We already have a no-fly list for potential terrorists....just add these flaming jerks to that list. How hard can it be?
Disobey a flight attendant, or become verbally abusive, and you're banned from flying for 5 years. Strike another passenger and it's 15. Strike a flight attendant, or sexually assault another passenger, and it's for life.
This is in addition to, not in place of, any other civil or criminal charges that your behavior may warrant.
Your work requires you to fly? Well, actions have consequences. You now need another job.
Given the 100% federal control, it hasn't been addressed only because nobody in Congress cares to.
