There’s a big difference between the teamsters defending drunk loading doc guys who don’t show up and the FOP protecting murders that kill unarmed compliant citizens.
So, are you saying (1) teamsters are better people than cops, or (2) the Teamsters Union is a better organization than the FOP, or (3) that violations of the law by people who are also union members should be evaluated on an individual basis? Or something else?
(FWIW, I've heard some great stories from engineers, about some of the work performed by members of various construction/trade unions! If you think 'loss of life' is limited to sub-standard police work, or members of LEO unions, think again... ;^)
