What is the legal test for offering money to induce a murder for hire?

Even if we were to accept the premise that an offer of money might, in some unlikely circumstances, be so large as to constitute outrageous government conduct, we do not believe a line should be drawn at a fixed dollar amount. Such an absolute line would be inconsistent with the flexible standards usually informing due process limitations. See Morrissey v. Brewer, 408 U.S. 471, 481, 92 S.Ct. 2593, 33 L.Ed.2d 484 (1972). An amount of money that might constitute a due process violation should be measured in relation to the inducement available for a particular criminal act from nongovernmental sources and the nature of the act itself. A large sum reflecting the going rate for a murder-for-hire might exceed due process limits if offered to induce the sale of a small quantity of marijuana.
