I'm also required by law to never exceed 55 mph on the highway. I break that one too. Thus far I have managed to evade the US Marshalls who are assuredly on my trail.
The penalty for driving 60 in a 55 is ever so slightly different than employing someone who you know or have constructive knowledge is an illegal immigrant.
In the former case, you get a $50 ticket.
In the latter case, you face from $100-$10,000 civil penalty for each illegal immigrant employed, and/or a $3,000 fine and six months in jail for a pattern of employing illegal immigrants.
