No one is forcing you to become a police officer. If you want special privileges (e.g. allowed to use deadly force) then you also get special responsibilities.
Why would it be dangerous ? As I said, that officer needs to account for all his actions during working hours anyway, so there should never be a problem proving his/her innocence.
Or to put it another way: if an officer has, say an hour, on a working day in which (s)he can't account for his/her whereabouts and actions, wouldn't that be a good reason to suspect and investigate that officer ? What was he/she doing in that time, why did he/she feel the need to drop 'off the grid' for an hour ? If they have nothing to hide, then why would it be a problem ?
Making the police officer career more risky by imposing arbitrary sanctions in case of bad luck isn't going to improve your chances of recruiting good police officers.
Yes, there are special responsibilities, but due process is important. If it's not happening, make that process work. Your approach is similar to "there is too much crime, let's make more laws so that more things are criminal".

No, it lowers the chances of recruiting bad apples. People don't do anything wrong and who keep the bodycam running all day have nothing to fear.

There is too much crime because the worst criminals work in law enforcement. This would be a way to weed them out.
