Forum:Shortcut to peaceful tour of entire city?

Believe it or not, the main reason I bought GTA IV was to peacefully tour the wonderful model of Liberty City which the clever Rockstar people built. Is there a simple cheat whereby I can do this? The key seems to be ending the police blockade of Algonquin / Manhattan. (I devised ways to get into it alive with the blockade in place, but could never manage to shake the police, save by hiding underground forever.)

POSTSCRIPT: I later found that if one uses the Grand Theft Auto: The Ballad of Gay Tony expansion pack, there is no problem doing a peaceful tour of the entire GTA IV universe.
 * The blockade will only dissapear after a number of completed missions. You can find more info here. Dodo8 Talk  08:44, February 12, 2014 (UTC)
