how did the suspect get away??

my apologies if this is a stupid question, i will be the first to admit that i literally know nothing about being a police officer, but how was the suspect able to get away from the entire police force?? isn't he supposed to be like under 6' and was running away on foot? again sorry if this is a stupid question, like everyone else i am very anxious and want this all to come to an end. but is this abnormal or to be expected that this guy is able to evade the police like that? this is a genuine question.
