I assume that you are saying that rules that limit what the police can do to catch a suspect, for example, jeopardize the right of the rest of us to be safe.
When the police are forced to abide by rules and such, you can say that our security is jeopardized. However, if they were not forced to abide by rules, our liberty would be jeopardized just as badly if not worse.
In other words, if there weren't limits on what the police could do, we would be more or less at their mercy. They could pretty much do whatever they wanted to pin any crime on any person.
So, if we didn't have the protections of the 4th, 5th, and 6th amendments, the police would be more of a danger to our rights than crimninals are now.
