I would invite to read an interesting article posted yesterday that states that "60 percent of new nonviolent, non-drug offenses lacked a criminal-intent requirement adequate to protect Americans who engaged in conduct that they did not know was illegal or otherwise wrongful from unjust criminal punishment."
It also indicated that "There are at least 5,000 federal criminal laws, with 10,000-300,000 regulations that can be enforced criminally."
You can’t get busted for destroying what you didn’t know what evidence. If you could we wouldn’t need trash collectors because nobody would ever get to get rid of anything.
