Swat is used in a variety of high-risk situations where it would not be safe for a uniformed officer to handle.  Some examples of situations where the SWAT team may be called upon are: hostage situations, barricaded suspects, dignitary protection, raids, and riots.  As well, the SWAT team may be called upon when there is a possible  threat to public safety, such as a terrorist attack, to observe special events from clandestine locations.
