The crime rate has decreased in the recent years and there is a prevailing believe that is in consequence of the technology development. I concur with this assertion as I think that security cameras and DNA testing prevail deter criminals and improve the crime situation.
First and foremost, it is quite common nowadays to install the security cameras at public places. Having knowing that they are filmed, people behave, so this prevents all type of crimes and inappropriate behavior as well, like shouting or climbing to monuments what is especially important in cases of juvenile crimes. Moreover, thousands of cases with missing and killed persons are solved due to the camera tapes where police peoples who followed the victim, so thousands of murders were not committed because the perpetrators remembered that they were on camera.
In addition, the technology are useful in solving crimes with DNA testing. The modern methods are able to get DNA from almost any surface and DNA is reserved for more than 50 years. Serial killers can be catches after first murders, saving many lives, and even the old cases are solved, where crimes were committed decades ago. Public sites with the DNA matches help police officers to find relatives of criminals, allowing them to narrow it down to the direct perpetrator.
In conclusion, the cameras and DNA testing are powerful deterrents for criminals, since people understand that the crime will be solved eventually and they will be sentenced. Thus, the technology progress reduces the crime rate around the world.
