Criminal Codes

Dear Mahalik, Criminology appeals to me because I have always been interested in crime and criminal justice, and I have also read your article which was very interesting. The managing of criminal investigations can be a difficult task to achieve. And many of the criminology these day use technology to track down there suspect and I think your solution is another great way of helping capture the criminals. And I also want to congratulate you for all the effort you have put into this work it is really helpful for the reality of this world and keep up the good work.

Question:

These criminals knowing that the investigators use there phone to track them down and decide to not use the phone are there other technology solution to this that you might have also discovered?
