It can not be used to prove that you actually did travel though. You can also put in only approximate address locations. Google isn't going to be running some inference algorithm to identify your most probable location or residence, they are just going to give LE the raw data. Unless you are a extremely wanted criminal, LE probably doesn't have the resources to do extensive analysis of google maps searches and a jury is not going to interpret those results the same way they would of actual location history.
