When that law is applied legally but in a spirit of entrapment, for citizens who
are otherwise law abiding, you now have �ivus hadin� perversion of the law.
“The location is known to have traffic police monitoring the street
for infractions on a consistent basis,” says YWN. And being
“otherwise law-abiding” doesn’t mean an instance of law-breaking
should be ignored.
(Also, I don’t think that’s how the term ivus hadin is usually used in a Torah context.)
