I don't get how your family was in danger, it's a 40cm Snake. You could easily use a broom to get it into a bucket or box and release it away from your house. Or just put a bucket over it, get some cardboard to slide under the bucket, flip it and without any danger it's in the bucket. Sometimes I think people just take what they see as the easy option. There are always other options other than a shovel or shotgun!!
