Hi, in this day and age of terrorism and school shootings, I realize we must be careful about what we say, post on the internet, and what we appear to believe. However, are we allowed to write songs about anything? Can we be investigated for what we write, and arrested for saying certain things? I would like to write from the first person pov about controversial elements, and I admit it is to shock and gain attention. Is it maybe a better idea to avoid such instinctive urges?
