I wasn't encouraging OP to enter tested meets while on PE, I was just stating the reality. I agree with both of you, but if you expect everyone in tested meets to be all time natural then I don't know what to tell you. The world isn't fair and there are people out there that will step on others and cheat just to get ahead. The people that aren't sensible enough to play it fair won't be deterred by a lecture on morality.
I am competing in a tested meet in June and I expect that there will be people there that are not natural considering that they will be testing only 10% of lifters at random. Will I be fuming at the meet, clenching my fists wishing hateful shit on them? Probably not. There is only so much you can do.
Edit: And to add to that, if you have probable cause to call someone out, by all means do it, but at the same time it will never be 100% fair. Unless of course every fed invests in sate of the art equipment and tests everyone year round. Which won't happen.
