Technology bad users

A lot of people use the technology to kill people, some of them to sell drugs, a lot of them to look for teenagers and a lot of them to steal. There are a lot of diferent types of people using the technology in a wrong way. Hackers look to steal information or money or anything, and this is bad for us, because we use the technology for good things, like, shopping while I'm at home. The other types of people use the technology to sell drugs. When drug dealers lose their phones they can't contact the people who want to buy some drugs so the phone is the main and most helpful tool for drug dealers. Also we have a lot of technologies that kill people, so we have to be careful of some of the technologies and the users.
