Yea I've never been a fan of the whole "makes law enforcement's job easier" arguments.

As though personal rights/liberties are trumped by a cop needing to do paperwork or leave his desk.

Plus, when you follow this to its natural/extreme conclusion, the absolute easiest thing for law enforcement would be to arrest you for no reason at all.

The rationalization for this policy of course could simply be that probable cause is "inconvenient."
