Cameras on ever person at any time have definitely made people more aware. A car driving from a crime scene has a very likely chance of being recorded from a security camera, etc. I think the moral ethics may have declined (can't leave your door open like you did in the 50's), but the technology has been a stronger force leaving less crime.
Because of the some effects of using technology instead of decreasing a crime its different for what we expected from it . Because of technology its can easily to do crime because the role of technology is to make our task easier that's why the criminal easy to do crime because of communication by using technology
