Please can you explain in 250 words minimum thank you very much in advance

Should it be illegal to include DeCSS software on a website merely because that software could be used in activities that would violate the law? WHY or WHY NOT? If so , should the sale of scissors, knives and razors also be banned from the Internet? Why or Why not? You must provide and explain an appropriate example(personal, article, etc) and make as valid argument for your opinions in support of your answers.
