I am not sure what the laws are in Texas, but here in Maryland someone actually has to be in the car before the police can try to bust them for DUI. Public intoxication, drunk and disorderly, and so forth are another story.
There seems to be a touge of misinformation and maybe a slight amount of hyperbole here.
It has been illegal for more than 50 years to be intoxicated in public in Texas. Public Intoxication is defined as "being intoxicated to the extent that you could be a danger to yourself or others"
If you do that while driving a blood alcohol test is necessary to prove you are drunk. Not so with Public Intoxication.
This charge may be overzealously prosecuted as can be Jaywalking. The story doesn't make the distincion clear. Freepers that leap to conclusions and over react should look at all sides of the issue (remember the Port Issue)They should also decide if they would like to sit in a bar with people that are drunk enough to be a danger to themselves or others.
