Ummm...lets see...
The boring thing about crime is that typically, the criminals are not too bright. Most crimes are the result of passion, stupidity, and lust. Very little is clever or thought out with any great deal of exactitude...that is typically just what you see in movies.
The hardest criminals to stop seem to be criminal organizations...those crimes that are run like a business...the more profit, the more careful and clever the criminals tend to be.
From what i have heard, the best way to get away with murder would be to simply kill someone who you are not connected with in anyway. This is what makes serial killers so very difficult to capture. When crime is random, the possibilities are endless.
Children typically commit crimes that are not well thought out. They typically are very short sighted and therefore commit shortsighted crimes. It is particularly disturbing when a child commits a heinous act...but typically not difficult to figure out because there is typically not much planning that goes into it.
The viciousness of a crime is typically taken into consideration when the punishment is being determined...as well as when the prosecutor is determining what to charge the individual with.
The more horrific the crime, the less likely it is that people will believe that a person can be rehabilitated which will of course play on the sentence.
Ok..there
:P
