Code unable to get the single tap, double tap correspondence to LEDs

My code is:

//Arduino 1.0+ Only!
//Arduino 1.0+ Only!

#include <Wire.h>

int ledPin= 6;
int ledPin1= 3;

ADXL345 adxl; //variable adxl is an instance of the ADXL345 library

void setup()
{
  pinMode(ledPin, HIGH);

  adxl.powerOn();
  

  //set activity/ inactivity thresholds (0-255)

  adxl.setInterruptMapping( ADXL345_INT_SINGLE_TAP_BIT,   ADXL345_INT1_PIN );
  adxl.setInterruptMapping( ADXL345_INT_DOUBLE_TAP_BIT,   ADXL345_INT1_PIN );

}

void loop(){

  // Output x,y,z values - Commented out

  //Serial.println(z);


  //Fun Stuff!    
  //read interrupts source and look for triggerd actions

    Serial.println("freefall");

  }

    Serial.println("double tap");
     //add code here to do when a 2X tap is sensed
     digitalWrite(ledPin, HIGH);
     delay(1000);
     digitalWrite(ledPin, LOW);
  delay(1000);
  }
  
  //tap
  if(adxl.triggered(interrupts, ADXL345_SINGLE_TAP)){
    Serial.println("tap");
     //add code here to do when activity is sensed
     digitalWrite(ledPin1, HIGH);

     digitalWrite(ledPin1, LOW);
  delay(1000);
  }
  
}

ledPin corresponds to PWM~6, and is colored red. ledPin1 corresponds to PWM~3, and is colored green.

As you can see in the code, the ledPin1 should be going off in the event that there is only a single tap. However, it is being finicky.

The following occurs:
when tapping the adxl345 once: green led. (sometimes) OR red led then green led
if tapping a second time close to the first, but not quite a double tap: red led then green led

When double tapping: red led lights up twice, then green led lights up once. (sometimes) OR the red led lights up once, and the green led lights up twice.

I am using an ADXL345 accelerometer.

Please let me know if you have more questions.

Moderator edit: CODE TAGS AGAIN. Please tell me - why is this so hard?
