Im so glad hes ok! I can understand all that you must be going through!
Ive been a paramedic for almost 9 years and every time I go to accidents caused by drivers who are DUI my blood boils. Fortunately in Australia they have what are termed "booze buses" where police will set up roadside testing facilities and stop all traffic passing on those roads to conduct random breath tests. If the test comes back as being positive for breath alcohol, the police will take them to the local hospital for blood tests, or, if the booze bus is set up, will take bloods then and there. The rate of DUI accidents has plummeted since police were given these powers.
I believe that doesnt happen in the States but would be a good thing if it did. Way too many people take way too many chances when they have been drinking, then decide to get in the car and drive home. I dont care if these people kill or injure themseelves from their own stupidity, its the people that are the inoocent ones I get emotional over.
