I agree. However, I also believe we've both seen too many Hollywood cop dramas. In real life cops are mere mortals who also shit their pants at the mere chance of bullets coming their way. Too many fellow Americans confuse cops with military combat veterans and I don't mean "combat" veterans who "won" authorization to wear a combat patch just for being in theater at the time of ongoing combat operations. Further, cops are trained in tactics not combat. That being said, many cops who joined the force sometime in the last twenty years are military combat vets, which is a different and as equally serious a problem as cowardice and self-preservation over duty.
I used to run a small business training local, state and federal law enforcement personnel in certain specific tactical skills I developed over a career in the US Army. On a number of occasions cops proved their unwillingness to do such basic cowboy up activities as standing in the rain, crawling through the mud, jumping across a narrow creek, and the like. Shit like that always lowered my faith just a bit in the ruggedness of the modern man. Myself, I grew up outdoors pretty much and was essentially a hard ass little commando by age ten. The army only further hardened and toughened up what was already there. You'd be surprised what a well trained, mission dedicated soldier is capable of doing. Your average cop ain't that but neither are most combat vets either. We're all human. Some of us, however, are unflinching even in the face of the greatest adversity, and we will hunt down the bad guys even if it's raining brimstone.
I will admit however that the gap between soldier and cop is narrowing greatly in America, at least from a paradigm shift and equipment point of view. These days even some patrol cops dress like soldiers, all tactical and web gear, cargo pants and plate carriers. But the man inside all that fancy kit is often nothing more than a heavily armed, frightened little boy who will do anything to get home to the wife.
