I too probably would have put my firearm in my vehicle. But the bottom line is, the man was breaking no laws and was deprived of his right to vote. I would love to see the ACLU and Justice Dept. look into this.
I can imagine when we get concealed carry here in Illinois there will be a lot of this, cops and officals making decisions based on what they "think" the law is when in fact the law prohibits, restricts or limits no such thing.
