After recently happening upon a paper titled, "Are Cops Constitutional," by Roger Roots, it has caused me to think about this topic. (http://www.constitution.org/lrev/roots/cops.htm) He essentially says that firstly, there was no police force like we know today when the Constitution was written. Secondly, that many aspects of ttoday's police force are unconstitutional. I'd say that the 10th Ammendment allows states to create a police force like we know today for the most part, however I'm not sure about federal police agencies. Wanted to get other opinions as well as input onto how true or false the claim that police work is unconstitutional really is. Thanks.
