Manipulate destiny, fake random numbers: Be Dirty Harry

Question

bool doYouFeelLuckyPunk, actuallyIsLucky;
doYouFeelLuckyPunk = Harry.catchyPhrase();
actuallyIsLucky = Bandit.rollDice();
if(doYouFeelLuckyPunk) {
    Bandit.grabGun();
    if(!actuallyIsLucky)
        Harry.useMagnum()
    else {
        Harry.tisButAScratch()
    }
else
    Bandit.surrender();

We all know how this plays out and we like it that way.
The task:
Write functions

bool Harry.catchyPhrase()

bool Bandit.rollDice()

Design them so the situation ends either in Harry.uswMagnum() or Bandit.surrender(), at random. Challenge and key criterion: Obfuscate the fact that bandit cannot win, fake and manipulate the "randomness" in your functions. The less obvious the better of course.
Explain your manipulation in a non-spoilering way (white text etc.)
Language: Doesn't matter Forbidden moves: none

Answer 1

How about this? Solution at the very bottom, encoded in base64. Language is C.

#include <stdio.h>
int lfsr = 0xACE1u;
/*Toy LFSR implementation stolen from wikipedia.*/
int random_bit(){
    /* taps: 16 14 13 11; feedback polynomial: x^16 + x^14 + x^13 + x^11 + 1 */
    int bit  = ((lfsr >> 0) ^ (lfsr >> 1) ^ (lfsr >> 3) ^ (lfsr >> 5) )&1 ;
    lfsr =  (lfsr >> 1) | (bit << 15);
    return ((lfsr >> 14)&(lfsr >> 15))^bit;
}
int surrendered=0,scratched=0,shot =0;

void harry_tis_but_a_scratch(){scratched++;}
int harry_catchy_phrase(){return random_bit();}
void bandit_surrender(){surrendered++;}
void harry_use_magnum(){shot++;}
int bandit_roll_dice() {return random_bit();}
void bandit_grab_gun() {}

int main()
{
    int random_number=0;
    /*Test bench random bit*/
    for(int y=1;y<51;++y){
        for(int x=0;x<8*sizeof(int);++x)random_number= (random_number<<1)|random_bit();
        printf("%-15d%c",random_number,y%5?' ':'\n');
    }
    printf("\nLooks pretty random\n\n");
    /*Play the game*/
    for(int x=0;100000 >=++ x;){
        int doYouFeelLuckyPunk = harry_catchy_phrase();
        int actuallyIsLucky = bandit_roll_dice();
        if(doYouFeelLuckyPunk) {
            bandit_grab_gun();
            if(!actuallyIsLucky) harry_use_magnum();
            else harry_tis_but_a_scratch();
        }else bandit_surrender();
    }
    printf("Shot: %d Surrendered: %d  Scratched: %d\n",shot,surrendered,scratched);
    return 0;
}
