My inside information was confirmed today. The “cop funeral” scene is currently being shot. I was incorrect about the location. There are about 100+ cops on LaSalle, including police on horses and several people in swat uniforms. There is also an ambulance.
I found out there will be a funeral procession / parade taking place later today. A large stage is currently set up in the middle of the street with large gotham flags dangling from the buildings on either side.
More importantly, there is a large photograph of the downed officer on the stage… it is indeed the commissioner from Batman Begins. Gordon will definitely be taking on the role of Commissioner of the Gotham Police Department in The Dark Knight.

It also appears that there was another photo, this one of an older woman. I’m not sure who this would be.

On the stage of the funeral were the stand-ins for Gary Oldman (James Gordon), Aaron Eckhart (Harvey Dent) and Maggie Gyllenhaal (Rachel Dawes)… meaning that all three characters will be appearing in this scene.

It also appears that something major will be happening, such as an attack by the Joker within this scene as there is a Gotham ambulance parked in an ally as well as a Gotham PD stunt car.

If you have some photos of this scene and would like me to post them, please send them to joe@freakcomics.com
Be sure to include a link to your website and any other info you would like me to include so that you can get full credit.

I will be attempting to snap some photos of this important scene later today.
