Thesis statement:downloading MP3 and videos without paying any money isnt legal and can not be on no account.
Reason 1:ıt is the same thing with theft.because you can easily download without any money although you dont have any permission.
Reason 2:people are commiting an offence with legal way and freely.
reason 3:Because you are impeding the others from gaining and making profit in their work.you are attacting their right.
opponent's idea:some may think that it must be legal since now it is very common and uncontrollable.also they say that costs are very high they cant afford them without it.
refutation of the opponent's idea:ı think it is not late for doing something.maybe it is vey commom and we wont stop this offence entirely.but we can decrease with making some precautions.
