Do you think there is any officer who is going to give you his consent to record him? The answer is no. However, you dont need his consent, you just need to inform him that it is being recorded.
Officers do not choose to install their own dashcams, it is department/agency policy for numerous reasons, mostly for support of later prosecution.
Also, what criminal traffic violations are you committing in Florida as there are very few and they would have little to do with what the officer says to you.
You arent eavesdropping on your own conversation, there are two people there. Thus, the conversation is meant only for those two people unless otherwise indicated (i.e. with notice of recording) and a recording would violate the privacy of that conversation since you are only one part of it.
I love how people bitch about the laws in this country. I suggest you travel to Eastern Europe and try this stuff there, or better yet South America.
I agree with the first part of your response that I just have to tell them that they're being recorded. That seems to be what most people are telling me.
However your explanation of eavesdropping makes no sense. If I am one of the two people in the conversation than why would I be charged with eavesdropping and not whoever hears it?
