Here is another suggestion:
The Mack Bolan saga of books at mackbolan.com are edge of your seat thrillers each one of them, if you can take the shooting of the bad guys. Mack has a code of morality that he sticks closely to: He has never ever shot a cop ever
and if he can help it never allows a bystander or someone on his team to get dead. There has been plenty of times that a bystander has been shot, however there was nothing mack could do about the matter. He has had several team mates killed in the line of duty but its not like he could do anything about it.
