It's my sister's husband. Why do you want to know? Has he broken a law or committed a crime?
In America, 2013? I'm sure it's a hate crime of some sort. In fact, I think if a New York City cop, who can randomly stop and frisk anyone, found that flag under your coat you could be charged with carrying a concealed symbol. And if the cop happened to be black he might feel threatened enough to pull his gun.
"Drop the flag! Hands up spread eagle!"
