A 50-year-old Army veteran who served in Iraq and Afghanistan was driving the parade float that investigators say edged across a railroad crossing in Texas despite warning signals of a fast approaching train, the man's attorney said Tuesday, Nov. 20, 2012. Four veterans and sixteen people were injured in the resulting collision. (AP Photo/Juan Carlos Llorca, File)
