- While much of the security planning for the NATO summit remains secret, some information about what the protective measures will look like has started to trickle out.
Last week, theU.S. Secret Service published bidding specifications for the work of putting up security barriers in the city for the May 20-21 summit that will bring leaders from around the world.
[...] Workers will have to put up 3,600 linear feet of “anti-scale” steel fencing, as well as 17,000 linear feet of concrete barricades. The fencing is currently stored at a federal facility in Maryland, while the concrete barriers will be supplied by local governments.
The specifications also call for 16-foot-wide “portable vehicle barriers” capable of stopping a 15,000-pound vehicle traveling at 30 mph. - As attention on security intensifies, the city announced Monday that a “routine military training exercise” would be under way in and around Chicago from April 16 to 19 to help personnel preparing for overseas deployment learn to “operate in urban environments.” A city spokeswoman said the training is done around the country and is not related to the NATO meeting.
We'd guess the "17,000 feet of concrete barricades" are the "Jersey walls" so prevalent around construction sites. That stuff isn't going to move.
A google search on the "anti-scale" stuff looks like wrought iron 12-15 feet high. No idea how that temporary stuff gets secured in place so as not to collapse or, worse, be used as a battering ram against security personnel...like cops.
