They ever so "politely" insisted that he give up his FFL.
And you said that he HAD to let them in. You are wrong, again.
Do not let the police into your house without a warrant that you have read at the very least. Better still have a lawyer present as well.
As an American citizen you have rights even if the JBT's and their crotch sniffers would prefer you did not. Use them.
“Yes, it did.
They ever so “politely” insisted that he give up his FFL.”
You are confused. That occurred during the subsequent raid and was OUTSIDE his house.
“And you said that he HAD to let them in. You are wrong, again.”
You are wrong again. I never said that.
