There are some benefits and consequences of copying or sharing work.  If you copy someones work they might have did it wrong and since you copied off of them then you'll get a bad grade.  Now if you copy someones work and they get it right then you will be in luck and get a better grade.  To detect plagiarism you can find out if it looks different then the same one someone else created.  The benefits of stricter copyright laws is how people don't copy off good peoples work.  Less strict copy laws will help people that like to share or copy work.  I think you should not be able to copy peoples work because they will just do the same thing and get more credit for it then the person that made it in the first place.
