RS does not file lawsuits. Tax disputes are civil matters. 90% of all IRS tax disputes are settled administratively. IRS has absolutely no authority to call on local law enforcement for anything. Local law is never involved in IRS tax disputes. If LE is necessary, US Marshals do the job. IRS does not cold call anyone and all contacts are initiated by US mail.
Received a call from Edwart Walter stating to be calling from the IRS and that I had a warrant out for my arrest for tax evasion. Demanded that I pay $9,000 in order not to get arrested.
