I have no problem with pregame requiring that the legal name be included on a pro's personal page. It may add problems to those pros who live in communities where public knowledge of their livelihood might have an effect on their families or professional life, but I really don't see this information putting anyone in physical jeopardy.
Anyone who lives in Las Vegas knows that if they have it in for a handicapper, they can pretty much find him or her at some public venue. Marco, Scotty, Ken, Fezzik, Bryan, RJ, Cokin, Pritchard, Youmans, Edel, Iskoe, Teddy Covers, (the list goes on) are all very public personalities and catching up with them would not be difficult. You might not be able to do them harm the day after you blow your 401K, but they are in the public quite often. And, I can't remember the last time I've heard of a handicapper getting whacked or even hurt by a disgruntled patron in Las Vegas.
But again, for those who live outside legalized sin, public disdain for the professional might be the biggest problem.
As for publishing criminal records, I'm not sure this is a good idea. People make mistakes. I certainly made enough of them when I was in my 20's and I would hate to think that they would be used against my right to make money 30 years later. Personally, I think this information should be disclosed to the powers that run pregame and then it's up to them if they wish to represent them as pregame handicappers. As a society, we like to give people a second chance, especially if they've done the time or made reparations for their screw-ups. I have no doubt that some of the older cappers at pregame have been arrested for booking or some boiler room operation, but in their time, that's what you had to do to make money in this business. And I certainly don't hold it against anyone.
I have a real estate license in California, and to get the license the state does an extensive background check on every applicant. Oddly enough, if you disclose all of your interactions with the law, the Board of Real Estate approves the application, with the exception of those known to burglarize. If you fail to disclose everything, they put on the brakes until everything is in order. But I would hate to see the Board of Real Estate require that Realtors disclose on their listings or farm materials: Convictions - Possession of Marijuana, Disturbing the Peace, Illegal Bookmaking, illegal fireworks, etc.
That would pretty much kill business.
Again, I have no problem that pregame does its own background checks and then weighing whether or not this particular pro is the kind of person they want to represent. Maybe they can make criminal records available to the public upon request and on a need-to-know kind of circumstance.
