I gotcha. Yes, I agree that governmental powers absolutely should be enumerated. My only caveat is that some of them must necessarily be of broader scope so that the mission isn't hamstrung. "Provide for the common defense" for example, could be broken down into a billion tiny powers. Some of which I absolutely think should not be included, but that's what the courts are (supposedly) for.
I agree that politicians and those in power believe clauses like the one you mentioned give them the authority to break it down into a billion tiny powers. But if they would pay attention to how the founders viewed clauses like that and the "welfare, and commerce" clause, they felt it was restricted by the 18 enumerated powers specifically spelled out. Of course we know that isn't the reality of modern bureaucrats.
RAS can definitely be an intrusion, I won't even try to deny that one. At the risk of invoking a famous Ben Franklin quote though, right up until an LEO sees a guy walking down a street with a paper bag in one hand and gun in the other and lets him go about his business because holding those two items isn't a crime. Then the community screams "Why didn't he stop the guy?! Clearly he was the one who robbed the bank ten minutes earlier! It was freaking obvious!". They can't win for losing if that's the case. The key is abuse of RAS, and that's a sticky wicket.
I know it does create hardships for those who are entrusted with Law Enforcement, and the general population really are mislead about the role LEO are supposed to have in a "free" society. Although I know what you posted is just an example, most states would make that situation illegal already, and most criminals conceal.
. But even if that wasn't the case, if I were a LEO in that situation there is nothing wrong with following the guy to the bank and stopping it in progress. But ideally an armed population would beat him to it.
Being in a front-row seat to see how our justice system currently works, I can tell you that I'm already pretty upset. I'll check out the book though!
Having been through the human meat grinder of our "justice" system I am upset too. I read books like this and by Napolitano, and Thomas E Woods, and I am better able to articulate why our system is not a justice system anymore.
