I'm afraid you appear to be something of an idiot. You are taking the wild and relatively unfounded accusations of one man and his team and pitting said accusations against a wealth of empirically investigated knowledge about the specifics. All evidence against the family and friends was contrived. The forensic scientists who discovered such "evidence" said in numerous interviews that what they had found did not support the claims of the police.
A country's police force is rarely incompetent, more likely misused.
