Something I've seen that is similar brought up before.

Bribe people not-to-witness a killing.

Simple stuff really, it brings back an element of risk and excitement to the game that was otherwise lost within several months of building yourself up to die suddenly and without purpose. Other to eliminate EVERYBODY.

It'd work like so, you want to wack someone, The option is there to bribe the witness/es to"not see" who did it. The cost would depend on age of character (rank doesn't mean much) and how much you don't want to be revealed. The cost would vary, depending on if you wanted to hide yourself completely or not.

Cost would equal=

Age of character + how much you want to be hidden + any extra expense you wanted to add.

Age of character would be the initial hit. 

10 days = 1,000000

20 days = 5,000000

30 days = 10,000,000

How much you want to be hidden would depend on what you pay to hide

Pay to hide your rank

Pay to hide your city

Pay to hide your crew

Pay to hide everything

The cost would mount up and you must really want this guy dead to pay to silence whoever sees your kill.

Depending on what you choose to hide would create issues in itself, a hit devised by a member revealing his city would create tension, even if the head of the city didn't auth it.

Could you take a bribe and not have the killer revealed? 

Think of all that money... how would you hide it??

Some example Witness Statements...

You WACKED! Fisk. The witness accepted the bribe.

Rumor has it someone in your crew accepted a bribe...

You accepted the bribe. The killer appeared to be a Capo from New York...

You accepted the bribe.

You WACKED! AlNeri. The witness declined the bribe!

I like the Idea. I mean it would take a bit of cash if you really wanted that person dead without anyone knowing,

I like this idea a lot :)

I like this idea, but I would change it just a little bit. Instead of leaving it up to the witness to accept/decline it, make all players decline it and all CAs accept it. This way, the chance is more in who snags the WS, rather than whether or not they want the money or the info.

I'm not sure I understand your thoughts, however one of the things I like about this idea is that it is an instant moral decision.

If someone pays 50mil + to hide their kill, you know it is a controversial kill. Declining it would mean you see something that could potentially start a war. 

However, that 50 mill would look very nice in your bank. You would have to keep it quiet. Your crew leader however would know someone accepted a bribe.

i like the idea
