how corrupt is the irish police force

Coffee with Doctor Barn.
I am complaining about the Irish police force, known incomprehensibly to most, by its Irish title An Garda Siochana.
A rough translation is guardians of the peace.
Dog rough.
I am fuming.
"They have replaced the international motto of policing, To Protect And Serve with a new motto of their own," I tell the brother hotly. "The Irish cops motto now is, To Harass And Intimidate."
Daktari remains non committal.
"You just don't like the police," he charges.
"I think they're individually and institutionally corrupt," I shoot back.
"They've brought down the road death rate," he persists.
I nod grimly.
"Mussolini made the trains run on time and put a temporary stop to the Mafia," I observe. "It wasn't worth it."
