Give me a few examples then where everyone is treated equally. It doesn't happen.
thats true. and those usually tend to fall into safety issues rather than politics. it makes sense to not sell an xm307 to some 15 year old from south chicago with gang tattoos all over his back. same thing with mental patients. but just because there are restrictions doesnt mean there should be.
doctors: you can try that, and as long as your patient agreed to the procedure, was notified that you had no license, and signed an affadvit agreeing to disburse you of legal liabilities, i dont think there would be much they could do about it. similar to drugs or herbs that have to state that their product isnt certified by the fda. buy at your own risk.
postal workers get those jeeps as part of their job. same way construction workers get backhoes and tower cranes as part of theirs. its not like they get to use that as their personal vehicle. (they might, but they arent supposed to)
i dont believe you can get in trouble for having lockpicks on you. now if the bank down the street just got robbed, and they catch you walking away with a set, thats suspicious but not illegal until they can prove you did it. The main thing is: possession of these tools with the intent to commit a crime. Therefore, the crime of possession of burglars tools is almost always combined with another crime, such as trespass or burglary.
politicians have those as job perks. highup executives in most companies get private jets, cars, golf courses, etc. and staff is usually not just needed, but does provide jobs. i do think, however, that most politicians are currently going way overboard with the amount of perks they enjoy.
