Re: Why is DNA profiling bad?

There's this assumption that DNA profiling is pretty foolproof, and that if an expert in a courtroom says your DNA was there, then it must true and thus you must be guilty.

But I did jury service recently and it's so important that you don't automatically make the last step above unthinkingly. There were two 'expert witnesses' who knew about fires, and they said it was very very unlikely that the fire had been started accidentally with a fag end. The prosecution used this to imply that the people smoking in the vicinity weren't responsible, and therefore it must have been the Accused, who set it deliberately.
But there was no proof of this final step at all - it could have been other people who started the fire, not the defendant. So we said he was not guilty.
- like the birmingham six or whoever, it looked like the police had presumed early on that he did it, and stopped looking for evidence that anyone else had done it.
Just because your dna's at the crime scene doesn't make you guilty! So why keep this database? It's not right. You're innocent until proven guilty. Do you want to live in a police state where your every move is monitored, just because a tiny minority of people commit crimes? It's ridiculous.
