OK, I’ll just answer plainly, and if I misunderstood you, feel free to correct me:
OP asked about the difference in Israel’s response to Munich and Gaza. I tried answering that to the best of my ability, as it seems most other answers didn’t correct the implicit assumption that Israel doesn’t go after Hamas’s leaders. If you think someone is “obsessed with Munich”, you should respond to the OP.
However, I get the feeling some people here took the question as “let’s use this question to further convince ourselves/others that Israel is committing genocide in Gaza”. In this context, your reply makes more sense when it’s addressed to me.
Obviously, it would depend on which country you’re asking.
No idea about the US, but what you’re describing has kinda been done. The PIs were hired for a set amount of time to track some politicians during the day, and were supplemented by freedom of information requests and data from public sources.
Most of the findings were what you would expect (Some parliament members barely came to the parliament, some had days with mostly political activists/lobbing/business magnate). There were a few “out there” examples, as one parliament member was doing grocery shopping etc. Thing is, this method is pretty good to figure out what politicians work for the public and who works for private interests, but it’s nearly impossible to actually uncover anything that’s even skirting on the illegal. A PI can’t wiretap or search private property.
A tangent, but In the same spirit, there’s a crowdfunded lobbying agency called Lobby 99.
