Sorry, not from the US. Who are the "blue stripe gang" please ?
no idea new one to me
Most likely the police.
"The 'thin blue line' is a term that typically refers to the concept of the police as the line which keeps society from descending into violent chaos."
In this case, referring to the police abuses of power.
@whiskywoman Thanks anyway.
@whiskywoman, @nogod4me Thank you, that is probably it, we have that here too, but with all the complex American symbolism like Red Hats going around, I was not sure.
Thank you for the response/comment.
