I did a search and didn't see this covered here. Although this only applies to Cook County If it passes It's very likely to spread to surrounding counties and so-on. Ring their phones if you oppose this ban.

ISRA Action Alert
Cook County Semi-Auto Ban to be voted on September 8
Attention Cook County residents, the future of your gun rights is in serious jeopardy:

On July 12, 2005 Cook County Board member Larry Suffredin introduced a county wide assault weapons ban. Under the provisions of this proposed ordinance, most of the semi automatic rifles, pistols, and shotguns you own would be banned and subject to confiscation by the Cook County Sheriff. The ordinance is currently assigned to the Boards committee on health and hospitals. Without your strong opposition to this proposal, it will likely be voted into law by the full Cook County Board during the September 8, 2005 board meeting.

Once the ordinance is passed, you will have 90 days to either demil semi automatic firearms, move them out of Cook County, or surrender them to the Cook County Sheriff. Should you fail to do so you will be subject to a $500 fine and up to 6 months in jail. Given the high profile of this ordinance, it is very likely that the Cook County Sheriff and Mayor Daley's CAGE unit will conduct midnight raids on gun owners homes as a publicity stunt to hype the ban.

ISRA urges you to call your Cook County Commissioner and ask them to vote against this oppressive ban. As usual this will have no effect on crime. It will only affect law abiding citizens.

To determine who your Commissioner is, look at your voters identification card next to Cty.Bd. The number(s) listed after is the district you're in.
