I am pretty sure we are coming from the same place here but I would like to point out anyway the hypocrisy of this seemingly strawman argument. If anyone has relocated to different states(like I have) they should know each one can be vastly different and for an issue as big as this and as impactful as this should not be left up to the states becuase of that fact. I again, realize I am just reiterating what has already been said but it is just so incredulous to believe that a percentage of the population thought that this was a good idea.
That is not true. They still need probable cause to detain you, and if they have that they can actually hold you up to a max of 72 hrs before they must file actual charges. But for a stop they can only detain you in so long to effect the investagory period. That can take however long but for say a traffic stop should be like 20-30 minutes.
