The known and the unknown… Are they?
One reason police investigations can take time is evasion and elusion. Villains deceive. That’s what they do. If every crime was as simple as it is made to seem then there would be no need for any police, courts, laws—in fact, if every first guess was right, we wouldn’t even need schools, books, or even language for that matter.
We wouldn’t even need protests, if all things were as they appear.
So, whomever you think the enemy is, just might be your friend. Whoever helps you fight him is probably your puppetmaster.
