it's like a lot of things in life...if we do it the right way, we get injustice, if we do it the way the powers-that-be want, we get...........injustice, just a different flavor.If police officers MUST read Miranda rights and follow strict procedures in arrests, we get criminals having too many loopholes....if we let police do it any way they wish, we get gratuitous beatings and innocent people getting harassed because some cops are just plain mean.
(...remember, several of OJ's jurors admitted that they knew from the beginning that they were NOT going to vote for conviction, no matter what the evidence said...this is what the system can lead to)
