ST. PAUL (AP) - Minnesota Gov. Mark Dayton says the Florida case involving Trayvon Martin's death in a scuffle with a neighborhood watch volunteer has stiffened his opposition to efforts to expand cases where lethal force is presumed legitimate.

Dayton commented Wednesday on the acquittal of George Zimmerman in Martin's 2012 death. Dayton says he personally believes Zimmerman "went way beyond what was called for in the situation."

He tied the case to proposals recently before Minnesota lawmakers to expand the stand-your-ground law in which people can use deadly force to defend themselves, their home or dwelling. A bill he vetoed in 2012 would have included hotel rooms, tent, cars and boats. Backers say potential victims of crime shouldn't have to retreat from aggressors.

Dayton says the Martin case underscores the need for limits.
