You had me up until this post...
The Police should only really be confiscating instruments of the crime, which guns are not. I find the argument that the guns were used to "guard drugs" incredibly weak as you can grow drugs without a gun and defend your home without drugs. First and foremost, you are protecting your life. Most people would still shoot at their raiders with drugs or without, meaning the resulting pile of bodies would generally look exactly the same.
Beyond this, the knowledge that your guns might be confiscated if a cop responds to your home being raided disincentivises defenders from co-operating with the Police. From my experience. this change has resulted in less aggressive interactions between home owners and the Police. I personally tend to be quite agreeable with defenders because I think it's incredibly obnoxious when cops go fishing for random bullshit to try to fuck over defenders when they happen upon their property.
