My son told me he was molested in boy scouts....

My son has had anger issues since he was in middle school. He's 17 now and has been in therapy since he was 15 and in boy scouts since he was 9 but I allowed him to stop going at 15. His dad is the main one who wanted him to be a boy scout. I just wanted him to go outside instead of hiding in a fire place reading. At 14 he came angry and started fighting with us. He pushed me into a door would hit his dad. It was so bad. He had a full mental break down when he was 15 and his older brother had to restrain him and he had him on the ground crying. I took him to therapy yesterday but this time they wanted me to stay... My son started crying. He was in a boy scout troop that had 3 different leaders. I 4-5th grade, another for 6-7th grade and the other was for the older boys. He said whenever they went camping his troop leader that was for the older boys started molesting him and would sneak into his tent... It started when he was 10 and went on. Then when he hit 8th grade that troop leader was now his and on the summer camping trip (before he had that huge melt down) he took him father by the lake and made him perform oral and have sex... My son is crying, I'm crying. Fir the first time in 3 years he hugged me and said he was sorry but I said "No. I'm sorry". His dad knows now to and when he told my husband he started bawling saying he was sorry and he never should have made him join. The only person who doesn't know is my oldest son right now. I just can't believe how evil the world can be. My sister when she was in girl scouts said she believed one the leaders was making her uncomfortable but I believed no one would do this... But I was so wrong..
