how corrupt is the irish police force

A recent court case has seen the acquittal by a corrupt Judge and a corrupt Jury of an Irish Army Captain and an Irish Police Officer who were in court facing charges arising from their joint assault on another man whose skull they opened with an iron bar.
I kid you not.
The Court acquitted.
But that's not what I want to tell you about.
I want to tell you about the Irish police officers, ironically styled the Garda Siochana or Guardians of the Peace, who investigated this attempted murder by an Irish Army Captain and his Irish Police Officer Accomplice of a third man whom they had randomly decided to execute.
(The third man is a British Army Commando of Irish ethnicity.)
Here's what the investigating police officers did:

1. The investigating Garda Police Officers deliberately mislaid their tape recorded interviews with the murderous Irish Army Captain and his Irish Police Officer accomplice.
2. The investigating Garda Police Officers deliberately mislaid the notes from their initial interviews with the guilty as sin murderous Irish Army Captain (still an army captain by the way) and his equally murderous equally guilty as sin Irish Police Officer accomplice.
3. The investigating Garda Police Officers deliberately mislaid the iron bar with which the murderously psychotic guilty as sin Irish Army Captain and his equally murderously psychotic guilty as sin Irish Police Officer accomplice had opened the skull of another man in attempting to murder him.

I give up.
Maybe our new Muslim over lords will return us to the rule of law.
