Ielts writing Task 2: ways to prepare

Do the benefits of increased security outweigh the drawbacks?

Here's my short, fast introduction:

It is true that the security in many cities has been tightened in recent years. Although I agree that some security measures can feel restrictive, I believe that there are more benefits than drawbacks.

Note:
- In reality, it might not be true that security has been increased in most cities, but I think we have to accept this in order to answer the question.
- The question gives us an example of increased security (video cameras), so we can definitely use that example in a paragraph about the drawbacks.
- Notice that my introduction paraphrases the question. I've used some of the words from the question, but there are some nice changes too (e.g. tightened, feel restrictive).
