The Bexar County jail facilities are at 200 North Comal in downtown San Antonio. In late 2012, press reports noted an increase in the number of suicides at the facility. The issue was a topic of debate in the election for sheriff that year.
A polar bear has one of the best noses in the entire world and are well known to have an incredible sense of smell. Polar bears have been seen walking in a straight line for 32km (20 miles) to food, with only their nose to guide them. Polar bears have also sniffed out a seal ten football fields away that was hidden under 1m (3') of ice.
We're not talking about hunting though. When you're hunting - it's okay if the animal runs 40-50 yards before bleeding out and dying. However, If you have a bear 30 feet away and closing fast, and your shot isn't going to kill it for 150 feet - guess what. Bear spray on the other hand will actually stop a bear in it's tracks.
