I think so. To me, it's like a cop who speeds and then pulls someone over for speeding the next day. It reminds me of a parent teaching their child - it's not 'Do as I say and not as I do' - It's got to be 'Do as I do'.
It also reminds me of an overweight doctor telling their patient to exercise, eat better, and lose weight.
How much respect are we to give to those who constantly live by 'Do as I say and not as I do'?
If the law is no tint beyond a certain darkness factor, then that law applies to everyone. They cannot be above the law.
