In view of the following, that doesn't sound reasonable to me!
No person shall be held to answer for a capital, or otherwise infamous crime, unless on a presentment or indictment of a Grand Jury, except in cases arising in the land or naval forces, or in the Militia, when in actual service in time of War or public danger; nor shall any person be subject for the same offense to be twice put in jeopardy of life or limb; nor shall be compelled in any criminal case to be a witness against himself, nor be deprived of life, liberty, or property, without due process of law; nor shall private property be taken for public use, without just compensation
I am not a legal authority. I understand the concept of just compensation.
The issue of how the weapons were seized would determine if it were an issue or not. I am sure there are circumstances where the law has been abused, but if the weapons were taken from someone committing burglary or drug trafficking it would seem reasonable.
Knowing Colorado Springs, I doubt the abuse would be an issue. In Chicago, then that is another matter.
I admit I do not have an informed opinion on the issue you cited.
