The answer is yes, they do.
The cops will not be looking for your guns when they arrest you, but at your arraignment, the Judge will order you to turn in any weapons, and body armor that you have in your possession. Body armor may seem like a defensive device, but the cops want to make sure they can kill you without too much effort.
Also, you will have to show proof that your bogus arrest case was dismissed before getting another permit. Even if your bogus arrest was expunged, it will still show up in the federal system, and HPD will deny you the permit based on that.
TROs. Someone files a TRO against you, and you will have to turn in your guns. A spouse only needs their testimony that they are afraid of you, to get the TRO. No other witnesses or physical evidence is needed.
Probable Cause. All the cops need to arrest you for a Felony is one witness who will testify against you. E.g. Somebody says that you pointed your finger at them in the shape of a gun = Felony Terroristic Threatening.
Also, in a Felony Terroristic Threatening Case, your gun registrations will be brought in to Court as evidence against you.
Of course the goal here, and around the country is to deny EVERYONE gun rights by making everyone a convicted Felon. Do a search on the number of convicted Felons in the US, and the number of convictions per year before you laugh.
Getting your guns back. If you happen to turn your guns into the HPD for some arrest, or TRO, don't assume that they will ever give them back to you. You may think that a court order from a judge will force the HPD to return your guns, but you could be wrong.
Also, the State AG has ruled that the HPD can give out your gun registration information to whoever they want, for whatever purpose.
I don't need any links for this info, because this is all from experience.
On a side note, cops lie in court all the time. They call it "testilying".

And let's keep the discussions civil.
