Senators hear another plea for sobriety check points.  Last session, after years of trying, supporters of sobriety check points finally got the Senate to go along, only to have the bill stopped in the House.  Dallas County Commissioner Ken Mayfield says they are coming back again because Texas still leads the nation in drunk driving deaths.  “There were 1269 lives which were lost in alcohol related deaths, that’s about 10 percent of what the national average is.”  He says check points can reduce the number of DWI accidents by about 20 percent.  That’s based on decades of data from other states that have had those checkpoints for many years.
