Can you imagine how embarrassing it would be if the secret service allowed him to serve the general public?

I mean, just off the top of my head ways that could go wrong:

• car bomb.
• sawed off shotgun
• normal shotgun in grandma’s minivan
• any assortment of pistols, including grampa’s .45 snubby.
• chemical attack (acid. Base. In a mug. Or weed spraying jug.)
• special mention to Novichok
• biologic (similar delivery.)
• nuclear. (Special mention to Russian polonium.)

This is all in addition to the risk that trump causes a grease fire (too bad it didn’t happen….)
