The only thing that concerns me about people wearing uniforms and medals they didn't earn is the potential ability to infiltrate actual military units with nefarious intent (like trying to sneak onto a military base).
Plenty of laws covering this. Stolen valor is the least of this person's concerns. Espionage and treason have some pretty stiff penalties...
Mom's comin' 'round to put it back the way it ought to be.
Anyone that thinks war is good is ignorant. Anyone that thinks war isn't needed is stupid.
