My perception was that the comment was correct however with a quick skim I cant produce anything more than anecdata. The police do seem to be consistently breaking their rules which dictate that the chase ends when it gets dangerous. However crashes do seem to be happen after the chase has ended rather too regularly - about 30 seconds later. Citation. Here is an editorial on the poor stats we have. An interesting aside - police chases followed by a crash kill far more people here than police guns.
