Some of his pardons are similar to those of Obama's but, there are those which are just egregious like the Black Water Security convicts. Then, to consider a 'pre-pardon', whereas those involved haven't been charged or even looked at, tells me that there some expected indictments on the way.

What’s that old saying “ You judge a person by the company they keep.” These pardons speak for themselves. Heard Bernie Madoff wants a pardon as well.
