I am always wary of statements that refer to “every”. Can you document that “every” comment? Probably not unless you have met “everyone” in the entire nation.
A more fair way of asking your question is "Can you QUALIFY that "every" comment?"
And the answer to that is "yes".
Jaywalking is against the law. Name a person who has NOT broken this law.
Driving a car with a burned out headlight, tail light, brake light, or running lights is illegal. Name a person who drives who has NOT broken this law.
Now, facing the fact that there are MILLIONS of laws in this country, it's a statistical certainty that EVERYBODY is going to violate SOME of these laws SOME of the time. Such laws run the full spectrum from capital crimes like murder all the way down to trivial laws like spitting on the sidewalk.
So again...ever eat anything before you bought it? Played gambling games for money in the privacy of your own home in a state where this is illegal? Engaged in any sexual activity other than penile/vaginal intercourse? Downloaded music, movies, TV shows, games which you did not pay for? Had in your possession permanent markers/spray paint in a jurisdiction with certain anti-graffiti laws? Illegally disposed of certain materials in the trash or environment in some areas, like batteries, oils, cleaning agents, old cell phones, or other toxic materials? Ever gone over the posted maximum speed limit? How about under the minimum posted speed limit? Or the old "rolling stop" maneuver? How about as a firearms owner and carried a firearm where it was prohibited? Driven through a state like Maryland or a place like DC with your weapon/ammunition not in strict compliance with the federal and local jurisdicational laws? Ever put your hands on someone to move them out of your way (assault)? Wolf-whistle a pretty lady in passing (sexual harassment)?
Obviously these are rhetorical questions and I really don't want to know the answers to them. Indeed, in some cases I wouldn't WANT you to answer them.
But the point is that even though most of us here are, in fact, pretty wary of over-generalized statements, SOMETIMES a generalization IS pretty accurate.
The one about "EVERY adult in the entire nation has broken laws" is one of those.
