Sad part is they(EMT's and Fire) are known to raise money for their nikkas in blue. Also, Fire departments also have a history of assisting cops in brutal assertion of white supremacy(The Birmingham fire hoses in 63, and Philadelphia Fire Department using firehoses to weaken housing structures in the MOVE bombing of '85.)
If you look up the thin blue line symbol, there's also thin lines for corrections officers, security guards, rescue people,etc. It's cult-like shyt.
I was at a protest in Harlem and when we got to a police precinct a fire truck drove by extra slow with their sirens on to drown out the chants. They stopped for a good minute so there was no emergency. NYFD has a history of not hiring blacks or Hispanics. They lost a discrimination case a while back.
