A phrase used to send respect to the "Boys in Blue" (police), that
originated in late 2014 after the killing of on-duty officers. The movement's ideology is the opposite of ACAB, and believes that all police deserve respect, and that any offense on killing an officer should be registered as a hate crime.
Though not always, the phrase is usually used as a counterphrase to "
Black Lives Matter", or "BLM", because that movement typically embodies anti-police ideologies.
Their flag is usually the US flag using only the colors black & white, along with a blue stripe replacing what would be a normal stripe, or just a
Thin Blue Line over a black background.
"Hey, did you see
the news story where a single officer took down over 3 criminals after a traffic-stop-gone-wrong?"
"Damn.
The people chanting ACAB always seem to forget
that Blue Lives Matter, and they nearly always do good rather than wrong."
