There is no probable cause listed in the bill.
Probable cause is what the cop comes up with to justify to a court the basis for his reason to believe you are in violation of law to justify appoaching you.
No probabable cause, i.e. no objective reason to believe a violation has occured, like the snitch next door watching you buy that car from Vinny, no cause to bother you.
I know what probable cause is, and the text of the bill that talks about audits, clearly says no probable cause is needed. If they think you may owe tax, guess what, they can audit you. Dispute what is clearly laid out in the bill. You make all these posts with big words and big thoughts, but you can't dispute simple points. Sometimes I really wonder.
