Glitter differs from company to company and can be used as evidence in a crime scene. Advances in crime fighting technology will eventually make it virtually impossible to get away with a crime someday. In fact, in several years time, we may be able to predict a crime before it even happens.
Yes, advances in crime fighting technology will make it impossible to get away with a crime someday because technology continues to grow. There are so many new advances in our modern society. DNA testing was not used even a few decades ago. Now it can prove who committed many crimes.
For every advance in technology that criminals can take advantage of, the government and law enforcement can always find a way to counter and that will remain the case far into the future. As soon as law enforcement comes up with a means to thwart criminals, they find new ways to avoid detection and the cycle continues. This is the way it has always been and there is little reason to believe that the future will be any different.
Just as there are new inventions to solve new and modern problems, people will always invent new ways to get hurt. There will be new ways to find evidence, but there will also be new ways to cover up that evidence. The sad fact that the crime shows don't tell you is that today, a great deal of crime still goes unsolved.
