I really hope you're joking with that comment.
No, there's merit in his claim.
A CSI is someone whose job is to establish the facts, which enable justice to be achieved.
Sure, sure....some are incompetent, & some are corrupt. But just as with most professions,
this is the exception rather than the rule. But a lawyer's job is different in that they're tasked
with advocating for one side, right or wrong. This means that on the order of 50% of the
time, they're tasked with pursuing evil.
And to top this off, they become judges, with the incentive of rigging the system to wring
the maximum of money from clients & taxpayers. So unlike most professions,
good lawyers
are the exception rather than the rule.
Good lawyers are where you find them. I was once sued (over $1M) by a guy whose
lawyer was a joy to do business with. Instead of being about fighting, he was about
the best solution. It was the only time I ever enjoyed being sued. He was a prince.
