First, we don't need to "know". We just need to find it likely for the suit to have merit. Secondly, we do "know" that Littlejohn broke the law because he's sitting in prison right now for his crimes. The probability that the IRS missed red flags in the vetting process in hiring him is very high based upon the nature and volume of his crimes. The IRS can and was held responsible for that failure per the settlement. Again, we don't need absolute "proof". Just a simple proponderance of the evidence. We don't have all the inside information right now but the facts here look pretty straightforward. We use facts available to us, not left-wing propaganda.
