No comment on Alex Jones himself, but on DUI. That threshold of .08 is very easy to achieve with just a few drinks, especially if consumed in a short period of time. It's a legal presumption of being intoxicated, although if you're a regular drinker, you're not "drunk" at that level. His other mistake was agreeing to take the "roadside sobriety tests." Those are made for you purposefully to fail; ALWAYS REFUSE to take them because the only thing you are doing is giving the police more evidence to use against you. If the cop goes all "So you are refusing a DUI test?" politely say "No, I will willingly take a blood/breath test but I'm not going to try to dance for you here on the street so you can use it against me." There is no law requiring you to submit to the roadside test and trust me, doing so will not work in your favor. Most of them you'd have trouble doing sober, add the stress of being pulled over and the police telling you to do silly things, like recite the alphabet backwards, and you're already set for failure. The "smelled of alcohol" and "redness of the eyes" are the other two standard lines that get put on every DUI arrest ever made.
Unbeknownst to many, blowing under that magical .08 doesn't always clear you either. In my state, there is DUI for blowing over the limit and DWI that you can be charged with blowing under the limit. Guess what? They both carry the same penalties, license suspension, fines, etc. So technically, you could have two or three beers while watching a sports game at the bar (wherever), blow a .04, and STILL get DWI even though you weren't over the limit.
The whole thing is a shitty racket between MADD, the police and lawyers. There's lots of money to be made! While I don't advocate anyone driving truly drunk, there is a huge difference between an old high school friend of mine, a raging alcoholic, that blew 3.8 (almost legally dead!) on a traffic stop and a casual drinker that blows at or under .08. The limit used to be a standard 1.0 and nationwide, it's been driven down to .08 because it's easier to get a conviction in court.
Know your DUI rights in your state. Understand them. Don't be afraid to cite them when needed during a traffic stop. Be honest about how much you had to drink and what you ate with the officer - "I had three beers during the game and a hamburger with fries (or whatever)." Unless you're falling down and slurring your words and stink of whisky, there's a good chance you'll be on your way, unless the cop just has a hard-on for you or you violated other traffic laws as part of the stop.
