How to prepare a perfect murder.
Step 1 - Choose a sport you think you're good at.
Step 2 - Train really hard until you perfect it.
Step 3 - Make sure you win either the olympics or become a one of the best in your field.
Step 4 - Turn Professional.
Step 5 - Make sure you make a fortune from sponsors, book sales and public appearances.
Step 6 - Suck up and be seen with influential people, make sure they always get tickets, autographs and valuable bits of kit you've used at prestige events. Don't forget to let them suck up to you so they can be seen with you.
Step 7 - Spend a lot of time and money on children's charities. (Might be a good idea to change that to endangered species at the moment)
Step 8 - Publicize your 'good deeds.'
OK. That's it: now you can kill whoever the fuck you want and get away with it.
I'm cynical? Don't know what you mean.
