C. holding that the government can usually satisfy its burden of demonstrating the propriety of an irs summons through an affidavit of one of its agents
D. holding that agents violation of irs regulations did not mandate exclusion of evidence obtained as a result of violation
E. holding that the principal is liable for an agents acts committed within the scope of the agents employment
