A Maryland state senator has crafted a bill to curb the zeal of public school officials who are tempted to suspend students as young as kindergarten for having things — or talking about things, or eating things — that represent guns, but aren’t actually anything like real guns. The bill also includes a section mandating counseling for school officials who fail to distinguish between guns and things that resemble guns. School officials who fail to make such a distinction more than once would face discipline themselves.
