It is categorically false. Police have radios, backup units, plainclothes units, dogs, helicopters, and some level of support from just about every citizen on the street. Where this happened, you are smack in the center of Cambridge in broad daylight with hundreds of witnesses and nearby patrol units. You can't outrun every witness on the street, or the officers summoned to the block ahead of you. It is absolutely ludicrous.

But for the sake of argument, let's assume he is the next Jason Bourne and manages to elude all of Cambridge, Boston, and MIT police on bicycle. What then? They clearly identified him on the street, so he knows they have his face. They also have his prints from the laptop, and the FBI probably has those filed from the PACER incident, so pulling his complete identity is only a matter of time. Staying at his job and place of residence is therefore out of the question. Does he pull a Whitey Bulger and go into hiding in some remote corner of the US? Give up contact with everybody that ever knew him and change his identity? Even Whitey got caught after 17 years, how long do you give a mild-mannered 24 year old with no ties to the criminal underworld? "Running faster" is only putting off the inevitable and adding charges to the docket.
