You obviously don`t understand what makes up Due Process. It is NOT Due Process to have your things taken and be taken into custody, THEN allow authorities to determine if there is an issue. Due Process happens BEFORE your rights and your freedom are taken.Well, that's a great missive about Jesus and Adams, but you never explained why, "the so called "red-flag" laws are very, very CLEARLY a constitutional breach".
Because there is in fact due process, I don't see it as un-constitutional.
