Interestingly one of the things that came out of 2020 was that nobody appears willing to control the police. Unless by police you mean FBI, which would both make sense for investigating a national politician and be directly under the control of the executive.
While I don't agree with that statement, I will clarify that I was using the term "police" to encompass all agencies in both USA and Canada capable of legally conducting an investigation at the federal level and carrying out an arrest. As far as I am aware, these agencies are all funded by our federal governments. Even though in my mind I was thinking of only the USA and Canada, the structural flaw probably applies to most governments, if not all governments ( speculating ). The flaw being that the leaders of our nations conduct national affairs as though they are shielded from the law policing its citizens. They are getting away with using our national resources ( financial, material, human etc ) in ways that may benefit their own agendas, but are observably harmful to our economy and therefore the citizens at large. If an investigation could prove that my speculation is true, then it would be in both our nation's best interest to deal with the problem both swiftly and legally. My hope would be that such an outcome would instigate reform to address the root cause. Without an investigation, we are at the mercy of waiting for the next election, but if our leaders are egregiously harming the interests our nations' citizens as a whole, we should not have to wait until their term is complete. I will add one more thing, the problem is not limited to economics. but also the abuse of the press and education to influence how we as a nation are able to learn about and understand both national and global politics.
