Case Study: “Letting the Big Ones Get Away – A Focus On Ethics” crashn Criminal Justice (CCJS100 Section 7980) – April 22, 2012 The case, as presented in the syllabus and the text book (Fuller, 2010), is very slim on the actual facts of the case.

After the second article told me you had to be in range of a tower, I went back to the first article and noticed my assumption was wrong. It also seems that the second article is giving me more information. I learned about “pings”, which is what your phone does when it is in range of the tower.

The argument that the same right applies to an individual’s electronic device because of the “search incident to arrest” doctrine, in my opinion, is in far reach of its bounds.
