in smaug that chicago has a particular police problem with regards to the use of deadly violence. in your studies, do you find something particular to chicago? is thawing worse statistically when you look at the facts than other communities, a problem that needs to be addressed there? >> well, you know, i guess chicago has a problem with constitutional racism, which is when i was in the prosecutor's office in 1997 researching and all the way through when i was still studying it while getting my phd, you saw police officers speaking in overt racist ways, prosecutors looking the other ways and racism legitimizing people's rights, shootings, like we saw in the lequan mcdonald case. that case is the case where we saw it on video, but there's many more like lequan mcdonald.
