Its surprising how many emergency service people and members of the public put their 'lifes on line' on perhaps a daily issue, and get no favours or rewards after the event.
Human nature is a very funny thing when sudden incidents occur, and 'the last thing on my mind' usually never comes into the scenerio. Its the after event that brings the shock and alarm, and 'did I really do that!'. You also usually at that stage, that the 'you should have never done that' comment comes into the investigation, which can leave a person with a slightly guilty complex, especially if its against the establishments health and safety guidelines.
Only recently we have heard about PCSO refusing to aid a drowning person, or police officers stopping the public from becoming involved with rescues of victims in house fires. The list is endless, but this only becomes 'public aware' when the media publishes these facts.
Who knows, perhaps you might be the next 'hero' or the 'idiot' for attempting to resolve an immediate and perhaps life saving or death issue!.
