This is a prime area where blockchain will come in and change government.

Down the road, these types of situations will not take place since all activity will be on the blockchain.

Right now, the money flows rules....the "public servant" you mentioned is basically bribed....we see that in the US with our Congress...their re-election wallets are filled by corporate entities (I know they arent allowed to do that) which effectively buys them influence.

This is not much different then the cash in an envelop put in a cake box like in Shawshank Redemption.
