everyone is not a physicist..still people have lot of gyaan to give..think deeply....a khukhri may not be flushed mere force of water...but think logically ..how do things get flushed ..its a pressure and thrust generated by force of water that pushes them inside.... when the force is manual and muscular...its much more than the generated by the amount water in a commode..... normally a person would find it dirty to push things inside the commode using his arms strength...however,...a person who wants to drain his murder weapon..would not really care about the dirtiness...but might still push it / force it inside the hole using his arms strength........if the force applied is sufficient the instrument might not come back to float ...but go down the drain....
Its not impossible ....though has to be studied well ..and i am sure anyone out of people who post comments about casting premature judgments would ever think of doing such experiments......there are people who can take care of the mechanism of the process..
Lets allow the experts do their jobs and spare the family in trauma who might have some hope of getting out of a possibly wrong accusation
