Earlier it was quite difficult to find criminal arrest records about a person because you would be required to fill out the application to the court of justice only and you were required to wait for a few days to get reply about your application. Some States did not allow disclosing the information to the public.
But today there is a huge difference just because of the internet which gives you free access to public criminal records online about anyone. Do a simple search in Google and the type of records your looking for and you will see many websites through which you can freely access criminal arrest records online. If the person whom you want to know had spent time in jail or prison then you can find out where and why the person was arrested. It is very easy to access free police arrest records online but sometimes it is not totally 100% free.
There is a big misconception that public records are free to access if someone is gaining access whether offline or online. Actually, you have to pay administrative fees for accessing the police reports and any other documents. But you have to pay only one time for getting detailed criminal history information about someone. If you do not pay for access to public criminal arrest records then you will get only basic information about the person and in most cases very inaccurate information as well.
The benefit of paying to access a detailed report of their criminal arrest records is that you will receive accurate and complete information about this person past.
