Tricking the outlet tester?

Suspicious of a single three prong outlet in a room of ungrounded outlets, I plugged in my outlet tester and got a two yellow light "correct". Pulled the cover and found the neutral white looped over the green screw. I converted the plug back to two prong.

Is there a different type of circuit tester that will see this if it is wrong?

Now I don't kow whether to trust this one or not...

I have never seen a plug in tester that could detect a bootleg ground.

I'm not aware of any method of detecting a bootleg ground, even theoretically. The trouble is that since ground and neutral go to the same place in the panel, these two configurations are electrically identical - unless something goes wrong. If something goes wrong (a loose or broken neutral), the bootleg ground is way worse than no ground at all.

Ideal makes a tester called a Sure Test Circuit Analyzer found here. I used one while inspecting in Camden all the time. It also checks voltage and current drop.
