I agree that she is using standard instant message abbreviations where there is a limit on the number of characters in a message. I can understand it because I do this with my 35 year old LE son sometimes. I see she signed in as a guest. If she is not used to forums such as this that do not have those limits, it is understandable to me she would think she had to communicate in IM format. I am sure she would communicate appropriately in regular settings such as classroom. Can we just address her concern? Whether she is a troll or not, which I doubt, then she will hear appropriate responses to her concern.
-----Wendyj, welcome to the forum. I see your concerns are that you have fears about firearms possessed illegally by criminals in the community. While the idea of firearms may scare you, I think you are expressing that you wish you had the means to protect yourself and your children in class. Since you did not identify where you live, it makes it difficult to suggest a direction as state laws differ. There are a number of states this year that have authorized special firearm training for teachers and to allow a limited number of teachers, determined by the principal to carry or have a firearm locked up in his or her room. The training in some states is similar to that taken by reserve officers, including shooting and gun safety and knowing all appropriate laws, including responsibilities of the person authorized to possess the firearm.
-----Just having a firearm is not enough. It is important if you want to become a firearm owner, even for your own protection, that you find someone locally qualified to train you and then get plenty of practice. Firearm safety is your number 1 priority. Most accidental shootings are the result of someone failing to follow correct safety procedures every time the firearm is outside of a gun safe or case or unlocked. It is healthy to respect what a firearm can do and to even have a little "fear" of it. This is the same sense of having "fear" to not drive when you are too exhausted to drive safely. If you get proper training, and practice, and consistently follow all safety rules, shooting is a fun sport. If you have specific questions and want to let us know where you teach, we might be able to address any specific concerns.
