I'm not sure where exactly your numbers came from for the trans percentage, but if we use the smaller percentage of .01% and the 2014 U.S. population of 318.9 million, that comes out to 31,890 trans people, nowhere near 3.8 million. That would change the murder rate to a 0.00072% chance, roughly 48 times the murder rate of white people from the numbers you gave. If you use the [i]much[/i] higher number, trans people still have about 1.5 times the murder rate. This should also require citations if you're going to claim it as facts and make such sweeping statements about the murders.
