TSG has the police report.
http://www.thesmokinggun.com/archive...61cheney1.html as you can see in the report the Kennedy County Sherrifs Office was contacted right after the accident. All this talk about with holding information about the incident is because the whitehouse didn't call a press conference immediately. so yeah they "witheld" the info from the press corps and contacted the local paper instead. oooooh conspiracy.
Oh, and it was a 28 gauge.
