This is one reason why, at least in the US, you should never talk to the police if you're suspected of a crime -- even if you're innocent and it seems that your innocence will be blindingly obvious to them[0]. Anything you say can and will be used against you, and by the rules of evidence, nothing you say to the police can be used for you in court. (Tell them you have a lawyer friend who will never let you live it down if you say anything without speaking to your attorney first.)

Don't do this unless you really have a lawyer friend. Lying to the police, even when you haven't committed a crime otherwise, can be prosecuted as obstruction.
It's better to simply say that you will not answer questions without an attorney present, then just stop talking.
I'm not a lawyer either, but I worked alongside law enforcement for most of my adult life.
How? Which political party or independents promote a policy to reduce police powers?
And even if there were, or are, any politicians with such a policy we ought to be more suspicious of them!
Policing is mostly local, so I think this is an area where there's a real chance to make things better. National politics are hopelessly tribal in the US, but city/county level politics are much less so. Go to city council meetings. Pay attention, and complain if they try to buy leftover military hardware like a BearCat[1]. Vote for and talk to your councillors. Organize a petition to de-militarize your local police force.
It's not "reducing police power", it's "even better training, tools and techniques for our hard-working police officers".
Aren't you assuming that people want something better? I don't know if that is true. Many people refuse to believe cops can be bad (due to ignorance or whatever other reasons)
