United States federal government should substantially decrease its authority

According to what you said, "they (police officers) do not know how to properly enforce the law without abusing it." Your argument against probable cause is based on cases in which officers did not enforce the law properly. If officers are not capable of enforcing the law properly, then changing the law and substantially decreasing the federal government's authority is not the solution. If officers can't enforce a law that has stood and worked since 1792, then the problem is not with the federal government, but with the individual state police systems. If the system is being abusive then it is the system that must be reformed, not the law that has stood since the founding fathers of the federal government adopted it. If police officers are trained properly to follow the law without abusing their power, then probable cause is used for its primary purposes: to spot criminal activity as it is occurring and prevent and reduce crime. The federal government should not decrease its authority because its authority reduces crime if enforced properly. Your initial argument was strictly about probable cause and the sense of smell used to justify the search of cars. Your discussion on stop and frisk is a red herring fallacy as it sidetracks from your main argument to distract from the issue you brought up in your premise. Even if you bring it up as an example, the example is still irrelevant as stop and frisk is a policy which, to be enforced, requires reasonable suspicion, not probable cause. The two are often wrongly used interchangeably as they have differing meanings and legal requirements. Furthermore, you again seem to be blaming the police for their wrongful actions implying that the police system should be reformed, while the debate is about the authority of the federal government. Your example is flawed as well since drivers are not stopped because of the smell of alcohol coming from their cars (it would have to be extremely strong for it to be smelled outside of the moving car), they are stopped because of a driving violation that may be as a result of alcohol consumption. Officers stop drivers not from a hunch but because of the improper driving that they witnessed. Then they may smell alcohol and possibly, legally search the car. As for your problem with my use of the word "hunch," I was using it in the way that you used it in round 1. You yourself said that the officer's hunch is also called "probable cause," but now you are saying that probable cause "is not a legitimate way to justify a reasonable suspicion of criminal activity." Perhaps "hunches" are not legitimate by their original definition, but by your definition, they imply probable cause. If you are going to redefine words then stick to your own definitions. It is unreasonable to call for the federal government to decrease its authority because of what happened in the 80s and 90s. Furthermore, your accusations of the federal government having too much authority and not using it in the right way are unsupported by any evidence. I showed you proof of the existence of all the federal agencies and what they strive to do, but you did not show me proof of how these agencies "can not seem to solve" all the problems you mentioned. "This could be proven with the current situation of the country," but you do not provide the proof of the current situation of the country. To claim that the agencies that exist to address the issues you mentioned are not doing their job is a claim that requires substance behind it. The federal government is using its authority to address these issues through the many agencies I showed you. How would these issues be resolved if the federal government had less authority to address them? Are you saying that with less authority the government would use its authority in "the right way?" What is "the right way?" Substantially decreasing the authority of the federal government would give the federal government less power to address pertinent issues. This would result in less of a chance for these issues to be solved so it is not sensible for the government to have its authority decreased.
