I didn't find the statistics that showed the win/loss ratio of fights that cops get into. Try again.
You said "good chance of being murdered". I gave you the statistics for cops killed in the line of duty and a link from that page to a break down of deaths from being shot, stabbed, strangled, etc. Sorry, but you are wrong. Cops are not being killed at a higher rate than they were 30 years ago. There is nothing in the statistics of police deaths to justify intrusive SWAT-type raids because "... 30 years ago when you lost a fight you just ended up with your butt kicked, and pride damaged. Before I retired, every cop knew that if he lost a fight he stood a good chance of being murdered. Times have changed." Time have not changed with respect to the number of cops killed in the line of duty from any cause, be it fights, traffic accidents, or choking on donuts. The numbers are essentially the same, even going down from a blip up in the 1920s and 1970s. In fact, 30 years ago, the number of cops killed in the line of duty was about a little less than twice what it is today and there are more cops on the force today making police duty by far more safe relatively speaking today than 30 years ago.
I notice that you provide nothing to back up your erroneous claim.
