As someone noted above, Michigan's carry laws vis-a-vis public schools are in flux. Current laws allow one who holds a valid CPL to carry in their vehicle while dropping off their own children or picking up same. An unintended consequence of legal wording has also been judged by Michigan State Police to allow current holders of CHL to carry OPENLY ONLY on school grounds. As you can imagine, anyone who chose to practice open carry on school grounds would gets LOTS of attention...especially these days. The legislature placed a new law on the governor's desk this week which, among other things, would revoke this (unintended) open carry provision in schools and replace it with increased concealed carry privileges-including public schools WHICH CHOOSE TO ALLOW IT-for those who meet additional training standards.
Michigan already has a two tier CHL system, but now only law enforcement/retired law enforcement folks have an "unrestricted" license while the rest of us have CPLs with a long list of NO CARRY zones. Should the governor choose to sign the bill on his desk, civilians who are willing to secure additional training requirements will be granted higher carry privileges.
Unfortunately, there is no uniform concealed carry policy or law from state to state and it is the responsibility of the one who carries to know that law at all times. Scary, huh!
